Warnings

'string' ('string':'integer') is triplex but doesn't have phases S set

• A triplex line has been used, but this triplex line does not have the phase S designated to indicate it contains single-phase components. Without this specified, you may get invalid results. See powerflow/triplex_line.cpp(76).

'string' ('string':'integer') parent 'string' ('string':'integer') does not export attach_enduse function so voltage response cannot be modeled

• Enduses must have a voltage source from a parent object that exports an attach_enduse function. The residential_enduse object references a parent object that does not conform with this requirement. Fix the parent reference and try again. See residential/residential_enduse.cpp(85).

'string' (auction:'integer') capacity_reference_property 'string' is not a double type property

• capacity_reference_property must specify a double property to work properly, and may behave unpredictably should it be pointed at non-double properties. See market/auction.cpp(347).

'string' (id:'integer') already has a link parented - this could give invalid answers in FBS!

• While connecting the different objects, a link's 'to' end already has another link as a parent. This is indicative of a loop or other 'non-radial' condition on the system. The exception to this is if an open switch is connected at that node. If it is not an open switch, Forward Backward-Sweep (FBS) will not give a proper solution in this condition. Even if it is an open switch, be aware that FBS could still give an invalid answer, depending on topological conditions. If it is an open switch, consider removing the open switch from your GLM to ensure proper answers. If it is another type of link or you do not wish to remove the open switch, consider using the Newton-Raphson (NR) solver instead. See powerflow/link.cpp(372).

'string' (id:'integer') is parented to a node, but has a link running into it!

• While connecting the different objects, a link's 'to' end already has a parent of another node. This may cause invalid answers on the system an an inaccurate powerflow. Please check the node's connection and adjust your system, if necessary. You may also consider using the Newton-Raphson solver (NR), which will not this issue. See powerflow/link.cpp(385).

'string' does not have a phase A to fault!

• A fault event was attempted on phase A of the link object. This object does not have a valid phase A to fault. See powerflow/link.cpp(5132).
• A fault event was attempted on phase A of the link object. This object does not have a valid phase A to fault. See powerflow/link.cpp(8020).

'string' does not have a phase B to fault!

• A fault event was attempted on phase B of the link object. This object does not have a valid phase B to fault. See powerflow/link.cpp(5161).
• A fault event was attempted on phase B of the link object. This object does not have a valid phase B to fault. See powerflow/link.cpp(8049).

'string' does not have a phase C to fault!

• A fault event was attempted on phase C of the link object. This object does not have a valid phase C to fault. See powerflow/link.cpp(5190).
• A fault event was attempted on phase C of the link object. This object does not have a valid phase C to fault. See powerflow/link.cpp(8078).

'string'('integer'): libraries not yet supported

• An attempt to use the library GLM directive was made. Library directives are not supported yet. See gldcore/load.c(4379).
• An attempt to parse a library GLM directive was made. Library directives are not supported yet. See gldcore/load.c(4789).

'string'('integer'): timezone 'string' is not defined

• The specified timezone is not defined in the timezone file .../etc/tzinfo.txt. Try using an known timezone, or add the desired timezone to the timezome file and try again. See gldcore/load.c(2454).

'string'('integer'): variable 'string' not found

• A macro refers to a variable that is not defined. Correct the variable reference, or define the variable before using it and try again. See gldcore/load.c(5889).

'string': controller price curve is not injective and may behave strangely

• The price curve 'changes directions' at the setpoint, which may create odd conditions in a number of circumstances. See market/controller.cpp(735).

'string': The transformer has reached its operational lifespan. Resetting transformer lifetime parameters.

• During the simulation, while using the transformer thermal aging model, the transformer reached the end of its life. It was assumed that the transformer was replaced with a new transformer of the same make, model, etc. to prevent failure of the simulation. All of the lifetime parameters are set to assume a "new" transformer. See powerflow/transformer.cpp(1211).

\'design_cooling_capacity\' not specified in parent ~ default to 5 ton or 60,000 Btu/hr

• The thermal_storage did not reference a parent object that publishes design_cooling_capacity, so 5 ton was assumed. Confirm or change the parent reference and try again. See residential/thermal_storage.cpp(214).

Afflicted object count went negative - using after fault count

• While determining the number of objects faulted by an event, a negative count was encountered. This indicates some objects magically restored themselves before the final count could be obtained. This may be a logic fault in the code, or the event generation logic. Pleas submit your code and a bug report using the trac website. See reliability/eventgen.cpp(920).

Afflicted secondary object count went negative - using after fault count

• While determining the number of objects secondarily faulted by an event, a negative count was encountered. This indicates some objects magically restored themselves before the final count could be obtained. This may be a logic fault in the code, or the event generation logic. Pleas submit your code and a bug report using the trac website. See reliability/eventgen.cpp(936).

All values in auction statistic calculations were skipped. Setting mean to zero.

• You may need to check your auction setup. At least two flags are used to skip values in the calculation of the statistics (ignore_pricecap & ignore_failedmarket). This error indicates that every value was skipped. This may be by design, but one should be aware of it. Note, standard deviation will also be set to zero after the initial statistics collection period. See market/auction.cpp(574).

Automatic controls can oscillate to the iteration limit with no time delays. To prevent this, ensure your switching limits are reasonable.

• With no time delays set (time_delay or dwell_time), the capacitor performs everything instantaneously. If the set points are too close together, the capacitor may oscillate until the convergence limit is reached. Avoid this for proper answers. See powerflow/capacitor.cpp(335).

Battery attempted to discharge too far!

• While attepting to initialize the battery, it encountered a negative or overloaded SOC condition. It has been arbitrarily set to 50%. See residential/evcharger_det.cpp(950).
• While attepting to initialize the battery, it encountered a negative or overloaded SOC condition. It has been arbitrarily set to 50%. See residential/evcharger_det.cpp(971).

Battery SOC calculation messed up and somehow went outsize 0 - 100 range!

• The initial battery SOC somehow ended up outside a 0 - 100% range. It has been forced to 50%. See residential/evcharger_det.cpp(930).

battery:'integer' 'string' - Deltamode is enabled for the module, but not this generator!

• The diesel_dg is not flagged for deltamode operations, yet deltamode simulations are enabled for the overall system. When deltamode triggers, this generator may no longer contribute to the system, until event-driven mode resumes. This could cause issues with the simulation. It is recommended all objects that support deltamode enable it. See generators/battery.cpp(272).

battery:'string' indicates it wants to run deltamode, but the module-level flag is not set!

• The diesel_dg object has the deltamode_inclusive flag set, but not the module-level enable_subsecond_models flag. The generator will not simulate any dynamics this way. See generators/battery.cpp(256).

bid_delay was less than the current minimum_timestep setting - rounded up to one whole timestep

• The time for bid_delay was less than the value set for minimum_timestep in the GLM. It was rounded to be at least one minimum_timestep in value. If this is not desired, fix your bid delay or minimum_timestep See market/generator_controller.cpp(472).

Capacitance calculation failure for 'string'

• While computing the capacitance, a zero-value denominator was encountered. Please check your underground_conductor parameter values and try again. See powerflow/underground_line.cpp(840).
• While computing the capacitance, a zero-value denominator was encountered. Please check your underground_conductor parameter values and try again. See powerflow/underground_line.cpp(966).

Capacitor 'string' has no pt_phase set, volt_var_control 'string' will pick the first phases_connected

• To properly operate capacitors from the volt_var_control object, a pt_phase property must be defined. One was missing, so the volt_var_control object assigned the first phase_connected value to pt_phase on that capacitor for proper operation. See powerflow/volt_var_control.cpp(1102).

Capacitor:'integer' - 'string' - the remote_sense object is a network_interface, node/link connections both enabled

• A capacitor has detected a network_interface object attached to the remote_sense object pointer. It will map this object to both the node and link options for remote telemetry. The capacitor operation method should specify the proper device to use, but this may have unintenteded consequences. See powerflow/capacitor.cpp(244).

Capacitor:'integer' does not have its upper voltage limit set.

• When under the VAR-VOLT control scheme, the voltage_set_high set point should be set to the upper voltage limit the capacitor will remain switched on for. See powerflow/capacitor.cpp(289).

Capacitor:'integer' does not have one or both of its current set points set.

• If the CURRENT control scheme is active, you must specify the current set points for the band of operation. Without these, the capacitor will not function and will effectively perform no action. See powerflow/capacitor.cpp(303).

Capacitor:'integer' does not have one or both of its VAr set points set.

• If VAR or VARVOLT control schemes are active, you must specify the reactive power set points for the band of operation. Without these, the capacitor will not function and will effectively perform no action. See powerflow/capacitor.cpp(296).

Capacitor:'integer' does not have one or both of its voltage set points set.

• If the VOLT control schemes is active, you must specify the voltage set points for the band of operation. Without these, the capacitor will not function and will effectively perform no action. See powerflow/capacitor.cpp(282).

Capacitor:'integer' has a secondary sensor specified, but is not in VARVOLT control. This will be ignored.

• The secondary remote sensor field is only used in the VAR-VOLT control scheme. When not under this control scheme, any inputs to this field are ignored. See powerflow/capacitor.cpp(225).

Capacitor:'integer' is set to manual bank mode, but does not know which phase to monitor.

• A capacitor is set to manual bank mode. However, pt_phase is empty and the capacitor does not know which phase to monitor to switch all conencted phases. Specify at least one phase in pt_phase to enable the bank control See powerflow/capacitor.cpp(356).

class_define_map(oclass='string',...): class 'string' does not assert UNSAFE_OVERRIDE_OMIT when parent class 'string' does

• A class is not asserting that it is unsafe to suppress synchronization behavior but its parent does assert that this is unsafe. This permits stealth omission by any classes that inherits behavior from this class and the warning is given in case this is not intended. See gldcore/class.c(722).

class_define_map(oclass='string',...): class 'string' suppresses parent class 'string' BOTTOMUP sync behavior by omitting override

• A class is suppressing the sync event implemented by its parent even though the parent is published with a flag that indicates this is unsafe. Presumably this is deliberate, but the warning is given just in case it's not intended. See gldcore/class.c(704).

class_define_map(oclass='string',...): class 'string' suppresses parent class 'string' POSTTOPDOWN sync behavior by omitting override

• A class is suppressing the postsync event implemented by its parent even though the parent is published with a flag that indicates this is unsafe. Presumably this is deliberate, but the warning is given just in case it's not intended. See gldcore/class.c(713).

class_define_map(oclass='string',...): class 'string' suppresses parent class 'string' PRETOPDOWN sync behavior by omitting override

• A class is suppressing the presync event implemented by its parent even though the parent is published with a flag that indicates this is unsafe. Presumably this is deliberate, but the warning is given just in case it's not intended. See gldcore/class.c(695).

class_find_property(CLASS *oclass='string', PROPERTYNAME name='string': property is deprecated

• You have done a search on a property that has been flagged as deprecated and will most likely not be supported soon. Correct the usage of this property to get rid of this message. See gldcore/class.c(202).

climate:'string' - Southern hemisphere solar position model may have issues

• The default solar position model was built around a northern hemisphere assumption. As such, it doesn't always produce completely accurate results for southern hemisphere locations. Calculated insolation values are approximately correct, but may show discrepancies against measured data. If this climate is associated with a solar object, use the SOLAR_TILT_MODEL SOLPOS to ensure proper results (this warning will still pop up). See climate/climate.cpp(763).

compare of strings using numeric op usually does not work

• An attempt to compare two numbers using a string comparison operation is not generally going to work as expected. Check that this is truly the desired comparison and correct it if not. If so and the warning error is not desired you may suppress warnings using #set warning=0 in the model file. See gldcore/find.c(139).

continuous_rating for link:'string' is zero - this may lead to odd warning messages about line limits with nonsense values

• The value for continuous_rating is set to zero for the particular link object. This may cause warnings related to line ratings that have nonsense values like '1.#J%'. To resolve these warnings, please put a valid number in for continuous_rating. Load order may also contribute to this problem. Ensure all configurations are first in the GLM files. See powerflow/link.cpp(539).

DC maximum power output is less than the real power output from the inverter. A higher DC power rating is recommended. Currently the VSI power output is not limited by the DC power output.

• DC maximum power output is less than the real power output from the inverter. Although currently inverter does not adjust its power output based on teh DC limitations. A higher DC power rating is recommended. See generators/inverter.cpp(3910).

debugger.conf was not found

• The debugger.conf was not found in the GLPATH environment path. This file is loaded when the debugger is enabled. Make sure that GLPATH includes the .../etc folder and try again. See gldcore/load.c(7210).

diesel_dg:'integer' 'string' - cannot set both Kd1 and Kd2 as 0 for the CVR conntrol! Have changed Kd2 to be 1

• The diesel_dg is not flagged for deltamode operations, yet deltamode simulations are enabled for the overall system. When deltamode triggers, this generator may no longer contribute to the system, until event-driven mode resumes. This could cause issues with the simulation. It is recommended all objects that support deltamode enable it. See generators/diesel_dg.cpp(1384).

diesel_dg:'integer' 'string' - Deltamode is enabled for the module, but not this generator!

• The diesel_dg is not flagged for deltamode operations, yet deltamode simulations are enabled for the overall system. When deltamode triggers, this generator may no longer contribute to the system, until event-driven mode resumes. This could cause issues with the simulation. It is recommended all objects that support deltamode enable it. See generators/controller_dg.cpp(280).

diesel_dg:'integer' 'string' - overload_limit has a value less than or equal to zero - set to 1.25

• The value for overload_limit in diesel_dg must be greater than zero. If it is not, it will be arbitrarily set to 1.25. Explicitly set this value, if this is not intended. See generators/diesel_dg.cpp(959).

diesel_dg:'integer' - 'string' has no parent object - default voltages being used

• The diesel_dg object does not have a proper parent -- default voltage values are used. See generators/diesel_dg.cpp(829).

diesel_dg:'string' - power_out_A is above 1/3 the total rating, capping

• The diesel_dg object has a power_out_A value that is above 1/3 the total rating. It will be thresholded to that level. See generators/diesel_dg.cpp(875).
• The diesel_dg object has a power_out_A value that is above 1/3 the total rating. It will be thresholded to that level. See generators/diesel_dg.cpp(1089).

diesel_dg:'string' - power_out_A is zero - arbitrarily setting to 50%%

• The diesel_dg object has a power_out_A value that is zero. This can cause the generator to never partake in the powerflow. It is being arbitrarily set to 50% of the per-phase rating. If this is undesired, please change the value. See generators/diesel_dg.cpp(1144).

diesel_dg:'string' - power_out_B is above 1/3 the total rating, capping

diesel_dg:'string' - power_out_C is zero - arbitrarily setting to 50%%

• The diesel_dg object has a power_out_C value that is zero. This can cause the generator to never partake in the powerflow. It is being arbitrarily set to 50% of the per-phase rating. If this is undesired, please change the value. See generators/diesel_dg.cpp(1168).

diesel_dg:'string' - rotor_speed_convergence is less than zero - negating

• The value specified for deltamode convergence, rotor_speed_convergence, is a negative value. It has been made positive. See generators/diesel_dg.cpp(1183).

diesel_dg:'string' - rotor_speed_convergence is zero - it may never exit deltamode!

• A zero value has been specified as the deltamode convergence criterion for rotor speed. This is an incredibly tight tolerance and may result in the system never converging and exiting deltamode. See generators/diesel_dg.cpp(1193).

diesel_dg:'string' - voltage convergence is enabled, but no exciter is present

• While performing simple checks on the voltage convergence criterion, no exciter is turned on. This convergence check does nothing in this situation -- it requires an exciter to function See generators/diesel_dg.cpp(1249).

diesel_dg:'string' - voltage_convergence is less than zero - negating

• The value specified for deltamode convergence, voltage_convergence, is a negative value. It has been made positive. See generators/diesel_dg.cpp(1259).

diesel_dg:'string' - voltage_convergence is zero - it may never exit deltamode!

• A zero value has been specified as the deltamode convergence criterion for voltage magnitude. This is an incredibly tight tolerance and may result in the system never converging and exiting deltamode. See generators/diesel_dg.cpp(1269).

diesel_dg:'string' did not have a valid Rated_V set, assuming 15 kV

• The Rated_V property was not set or was invalid. It is being forced to 15 kV, which aligns with the base for all default parameters. This will be checked again later to see if it matches the connecting point. If this value is not desired, please set it manually. See generators/diesel_dg.cpp(974).

diesel_dg:'string' did not have a valid Rated_VA set, assuming 10 MVA

• The Rated_VA value was not set or was set to a negative number. It is being forced to 10 MVA, which is the machine base for all of the other default parameter values. See generators/diesel_dg.cpp(945).

diesel_dg:'string' did not have a valid Rated_VA set, assuming 5000 kVA

• The Rated_VA value was not set or was set to a negative number. It is being forced to 5000 kVA, which is the machine base for all of the other default parameter values. See generators/diesel_dg.cpp(862).

diesel_dg:'string' forced into DYN_SYNCHRONOUS mode

• The diesel_dg object had the deltamode_inclusive flag set, but was not of the DYN_SYNCHRONOUS type. It has been forced to this type. If this is not desired, please remove the deltamode_inclusive flag or explicitly set it to false. See generators/diesel_dg.cpp(847).

diesel_dg:'string' indicates it wants to run deltamode, but the module-level flag is not set!

• The diesel_dg object has the deltamode_inclusive flag set, but not the module-level enable_subsecond_models flag. The generator will not simulate any dynamics this way. See generators/controller_dg.cpp(255).
• The diesel_dg object has the deltamode_inclusive flag set, but not the module-level enable_subsecond_models flag. The generator will not simulate any dynamics this way. See generators/diesel_dg.cpp(1306).

Efficiency unspecified - defaulted to 'real' for this inverter type

• An inverter_efficiency value was not explicitly specified for this inverter. A default value was specified in its place. If the default value is not acceptable, please explicitly set inverter_efficiency in the GLM file. See generators/inverter.cpp(1135).

emergency_rating for link:'string' is zero - this may lead to odd warning messages about line limits with nonsense values

• The value for emergency_rating is set to zero for the particular link object. This may cause warnings related to line ratings that have nonsense values like '1.#J%'. To resolve these warnings, please put a valid number in for emergency_rating. Load order may also contribute to this problem. Ensure all configurations are first in the GLM files. See powerflow/link.cpp(549).

Empty powerflow connectivity matrix for island 'integer', your system is empty!

• Newton-Raphson has an empty admittance matrix that it is trying to solve. Either the whole system faulted, or something is not properly defined. Please try again. If the problem persists, please submit your code and a bug report via the trac website. See powerflow/solver_nr.cpp(3255).

Empty powerflow connectivity matrix, your system is empty!

• Newton-Raphson has an empty admittance matrix that it is trying to solve. Either the whole system faulted, or something is not properly defined. Please try again. If the problem persists, please submit your code and a bug report via the trac website. See powerflow/solver_nr.cpp(3264).

evcharger_det:'string' - the breaker rating may be too low for this maximum charge rate.

• The evcharger_det maximum_charge_rate and configuration calculated a maximum breaker current that may be above the current setting. This may cause the breaker to trip and affect simulation results. If this is undesired, set the breaker_amps property to a higher value. See residential/evcharger_det.cpp(196).

evcharger_det:'string' - The max charge rate is over 1.7 kW (Level 1), but the load is still 110-V connected.

• The evcharger_det maximum_charge_rate implies a level 2 or higher charge rate, but it still set up to be connected as a normal level 1 110/120 VAC device. This may cause issues with circuit breakers tripping. If this is undesired, be sure to specify the proper configuration property. See residential/evcharger_det.cpp(174).

event_gen:'string' does not have a metrics object as a parent -- metrics are not calculated.

• The event_gen object needs to be parented to a metrics object to ensure reliability metrics are being properly computed. Please ensure the parent of this event_gen object is specified, and is a metrics object if reliability metrics are desired. See reliability/eventgen.cpp(256).

event_gen:'string' has the ability to generate more than 1 simultaneous fault - metrics may not be accurate

• The event_gen object has the ability to induce simultaneous and concurrent fault conditions. This may affect the accuracy of your reliability metrics. See reliability/eventgen.cpp(658).

eventgen:'string' - minimum_timestep set - all events at least 1 minimum step long

• A minimum timestep value is set in the file. Reliability works not-so-well when the events are starting and stopping less than this value. All events are therefore going to be set to be at least 1 minimum timestep long. This may alter your results, so please plan appropriately. See reliability/eventgen.cpp(191).

eventgen:'string' indicates it wants to run deltamode, but the module-level flag is not set!

• The eventgen object has the deltamode_inclusive flag set, but not the module-level enable_subsecond_models flag. The event will not simulate any dynamics this way. See reliability/eventgen.cpp(681).

Eventgen:'string' is flagged for deltamode, but reliability deltamode is not enabled

• The deltamode flag was set for the particular eventgen object, but the enabled_subsecond_models flag for the entire reliability module is not set. Deltamode support is not enabled. If this is not desired, be sure to set the module-level variable enabled_subsecond_models to true and try again. See reliability/eventgen.cpp(221).

explicit 'string' model is experimental

• The clothes washer explicit model has some serious issues and should be considered for complete removal. It is highly suggested that this model NOT be used. See residential/clotheswasher.cpp(155).
• The refrigerator explicit model has some serious issues and should be considered for complete removal. It is highly suggested that this model NOT be used. See residential/refrigerator.cpp(151).

explicit 'string' model is experimental and has not been validated

• The dishwasher explicit model has some serious issues and should be considered for complete removal. It is highly suggested that this model NOT be used. See residential/dishwasher.cpp(178).

Failure to load solver_'string' as a library, defaulting to superLU

• While attempting to load the DLL for an external LU solver, the file did not appear to meet the libary specifications. superLU is being used instead. Please check the library file and try again. See powerflow/node.cpp(805).

Failure to map deltamode function for device:'string'

• Attempts to map up the interupdate function of a specific device failed. Please try again and ensure the object supports deltamode. The object simply may not support delta mode. If the error persists, please submit your code and a bug report via the trac website. See powerflow/link.cpp(2680).
• Attempts to map up the interupdate function of a specific device failed. Please try again and ensure the object supports deltamode. This error may simply be an indication that the object of interest does not support deltamode. If the error persists and the object does, please submit your code and a bug report via the trac website. See powerflow/node.cpp(1785).

Failure to map deltamode saturation function for device:'string'

• Attempts to map up the saturation function of a specific device (transformer) failed. Please try again. If the error persists, please submit your code and a bug report via the ticking website. See powerflow/link.cpp(2703).

Failure to map VFD current injection update for device:'string'

• Attempts to map a function for the proper VFD updates did not work. Please try again, making sure this node is connected to a VFD properly. If the error persists, please submit an issue ticket. See powerflow/node.cpp(5240).

fault_check interaction with restoration requires meshed checking mode - enabling this now

• The restoration algorithm is improved by using the meshed mode of topology checking for faults. This has been automatically enabled for the object. If this is undesired, do not use fault_check with restoration. See powerflow/fault_check.cpp(234).

fault_check:'string' was forced into meshed search mode due to multiple grids being desired

• While starting up a fault_check object, the grid_association flag was set. This flag requires the meshed topology checking routines to be active, so that capability was enabled. If this is undesired, please deactivate grid_association capability. See powerflow/fault_check.cpp(145).

file 'string' ignored in test mode

• This warning is caused by an attempt to read an input file in self-test mode. The use of self-test model precludes reading model files. Try running the system in normal more or leaving off the model file name. See gldcore/cmdarg.c(1442).

Fuse status updated, but no other changes made.

• When changed under solver methods other than NR, only the fuse status is changed. The solver handles other details in a specific step, so no other changes are performed. See powerflow/fuse.cpp(859).

Fuse:'string' fuse_resistance has been set to zero. This will result singular matrix. Setting to the global default.

• Under Newton-Raphson solution method the impedance matrix cannot be a singular matrix for the inversion process. Change the value of fuse_resistance to something small but larger that zero. See powerflow/fuse.cpp(192).

Fuse:'string' has a negative or 0 mean replacement time - defaulting to 1 hour

• A fuse has a negative or zero time specified for mean_replacement_time. The value has therefore been overridden to 1 hour. If this is unacceptable, please change the value in your GLM file. See powerflow/fuse.cpp(168).

fuse:'string' has a zero current limit - set to 9999.9 Amps

• A fuse somehow had a current limit of 0.0 Amps set. This is invalid, so a placeholder value of 9999.0 Amps is used. Please adjust this value accordingly. See powerflow/fuse.cpp(159).

Fuses only work for the attached node in the FBS solver, not any deeper.

• Under the Forward-Back sweep method, fuses can only affect their directly attached downstream node. Due to the nature of the FBS algorithm, nodes further downstream (especially constant current loads) will cause an oscillatory nature in the voltage and current injections, so they will no longer be accurate. Either ignore these values or figure out a way to work around this limitation (player objects). See powerflow/fuse.cpp(181).

generator_controller:'string' entered an unexpected state - results may be invalid!

• While determining the output state for the generator, an unexpected condition was encountered (it was turned on when it expected to be off, or vice-versa). This means all subsequent bids are suspect or incorrect. Please ensure nothing has changed cleared markets before the latency period expired. If this message persists, please submit your code and a bug report via the trac website. See market/generator_controller.cpp(1306).

Generator_rating and bid_generator_rating both have values in generator_controller:'string'

• Both the generator_rating and bid_generator_rating have non-zero values at the start of the simulation. bid_generator_rating will eventually override generator_rating, so please ensure your values are entered appropriately. See market/generator_controller.cpp(337).

global_create(char *name='string',...): property 'string' unit 'string' is not recognized

house_e:'integer' 'string' - Deltamode is enabled for the module, but not this house!

• The house is not flagged for deltamode operations, yet deltamode simulations are enabled for the overall system. When deltamode triggers, this house may no longer contribute to the system, until event-driven mode resumes. This could cause issues with the simulation. It is recommended all objects that support deltamode enable it. See residential/house_e.cpp(1746).

house_e:'string' indicates it wants to run deltamode, but the module-level flag is not set!

• The house_e object has the deltamode_inclusive flag set, but not the module-level enable_subsecond_models flag. The house will not simulate any dynamics this way. See residential/house_e.cpp(1728).

impedance1 was defined, but impedance2 was not -- assuming they are equal

• One of the secondary side impedances (impedance1 or impedance2, or resistance1 and reactance1) was set to a non-zero value, indicating you wanted to use the secondary impedances, however, the other value was not also set. If you do not want to use the assumption that they are the same, please set the other impedance value. See powerflow/transformer_configuration.cpp(270).

impedance2 was defined, but impedance1 was not -- assuming they are equal

• One of the secondary side impedances (impedance1 or impedance2, or resistance1 and reactance1) was set to a non-zero value, indicating you wanted to use the secondary impedances, however, the other value was not also set.

See powerflow/restoration.cpp(250).

Init() triplex_node (name:'string', id:'integer'): Phases specified did not include phase S. Adding phase S.

• Triplex nodes and meters require a single phase and a phase S component (for split-phase). This particular triplex object did not include it, so it is being added. See powerflow/triplex_node.cpp(181).

init(): Rated_kVA or {area or rated insolation or effiency} were not specified or specified as zero. Leads to maximum power output of 0.

• The relationship between power output and other physical variables is described by Rated_kVA = Rated_Insolation * efficiency * area. Since Rated_kVA was not specified and this equation leads to a value of zero, the output of the model is likely to be no power at all times. See generators/solar.cpp(601).

init(): Rated_kVA, efficiency, Rate_Insolation, and area did not calculated to the same value. Ignoring Rated_kVA.

• The relationship between power output and other physical variables is described by Rated_kVA = Rated_Insolation * efficiency * area. However, the model can be overspecified. In the case that it is, we have defaulted to old versions of GridLAB-D and ignored the Rated_kVA and re-calculated it using the other values. If you would like to use Rated_kVA, please only specify Rated_Insolation and Rated_kVA. See generators/solar.cpp(614).

No fault_check object present - Newton-Raphson solver may fail!

• A fuse blew and created an open link. If the system is not meshed, the Newton-Raphson solver will likely fail. Theoretically, this should be a quick fail due to a singular matrix. However, the system occasionally gets stuck and will exhaust iteration cycles before continuing. If the fuse is blowing and the NR solver still iterates for a long time, this may be the case. See powerflow/fuse.cpp(625).

Node:'string' is parented to a swing node and will get folded into it.

• When a node has the parent field populated, it is assumed this is for a "zero-length" line connection. If a swing node is specified, it will assume the node is linked to the swing node via a zero-length connection. If this is undesired, remove the parenting to the swing node. See powerflow/node.cpp(583).

NR: A matrix dump was requested, but no filename was specified. No dump will occur

• The powerflow module was configured such that a Newton-Raphson-based matrix dump was desired. However, no file was specified in NR_matrix_file. No output will be performed. See powerflow/node.cpp(1697).

Object 'string' (node:'integer') is flagged for deltamode, but it's parent is not. This may lead to incorrect answers!

• A childed node's parent is not flagged for deltamode. This may lead to some erroneous errors in the powerflow. Please apply the flags DELTAMODE property to the parent, or utilize the all_powerflow_delta module-level flag to fix this. See powerflow/node.cpp(1241).

Only WYE-WYE configurations are working in either Newton-Raphson or non-Manual controls

pw_load::init(): power_threshold is zero, convergence may not occur!

• pw_load has a zero value for power_threshold. It attempted to guess a value using the connected load inside PowerWorld, but that was 0 as well. This results in an extremely tight convergence criterion and may fail. Specify a manual value to ensure convergence. See network/pw_load.cpp(667).

pw_load::init(): power_threshold was zero, set to 0.1%% of load - 'real' MVA

• pw_load had a zero value for power_threshold. The solver pulled the current value from the connected PowerWorld load and will use 0.1% of its VA value as the convergence criterion. If this is too loose or otherwise unacceptable, specify a manual convergence value. See network/pw_load.cpp(676).

random_bernoulli(p='real'): p is not between 0 and 1

• An attempt to generate a random number used a parameter that was outside the expected range of real numbers. Correct the functional definition of the random number and try again. See gldcore/random.c(362).

random_bernoulli(p='real'): p is not within the normal bounds of +/-1e(+/-30)

• An attempt to generate a random number used a parameter that was outside the expected range of real numbers. Correct the functional definition of the random number and try again. See gldcore/random.c(356).

random_degenerate(a='real'): a is outside normal bounds of +/-1e(+/-30)

range:'integer' is using an experimental model and should not be considered reliable

• The range object has a number of VERY experimental features and development is incomplete. If you are receiving this error message, reccommend no longer using this particular feature without considerable overhaul. See residential/range.cpp(469).

Regulator 'string' has phase 'character' at the maximum tap value

• The regulator has set its taps such that it is at the maximum setting. This may indicate a problem with settings, or your system. See powerflow/regulator.cpp(1007).

Regulator 'string' has phase 'character' at the minimum tap value

• The regulator has set its taps such that it is at the minimum setting. This may indicate a problem with settings, or your system. See powerflow/regulator.cpp(1034).

Regulator:'string' regulator_resistance has been set to zero. This will result singular matrix. Setting to the global default.

• Under Newton-Raphson solution method the impedance matrix cannot be a singular matrix for the inversion process. Change the value of regulator_resistance to something small but larger that zero. See powerflow/regulator.cpp(286).

Restoration object not detected!

• The fault_check object can use a restoration object in the system. If the restoration object is present, unsuccessful node support checks will call the reconfiguration. See powerflow/fault_check.cpp(1889).

restoration: Attempt to parse complex CSV array resulted in an empty array - check your inputs

• While attempting to parse a comma-separated string into a complex array, the array appears to be empty. Ensure this is the correct behavior. See powerflow/restoration.cpp(1175).

restoration: Attempt to parse double CSV array resulted in an empty array - check your inputs

• While attempting to parse a comma-separated string into a double array, the array appears to be empty. Ensure this is the correct behavior. See powerflow/restoration.cpp(966).

restoration: Attempt to parse object CSV array resulted in an empty array - check your inputs

• While attempting to parse a comma-separated string into a object array, the array appears to be empty. Ensure this is the correct behavior. See powerflow/restoration.cpp(1300).

restoration: The source vertex for the reconfiguration is not defined, defaulting to a swing bus

• To properly operate, the reconfiguration needs the sources vertex of the system defined. If left blank, the first SWING bus will be utilized instead. See powerflow/restoration.cpp(503).

Reverse real power flow detected at generator switch 'string', generator is absorbing real power now!

• The diesel generator is absorbing real power, which is not allowed. Should check kVA rating and power_out_A/power_out_B/power_out_C value settings. Large kVA rating, or small initial power output than the total loads may result in negative real power output calculated. See generators/controller_dg.cpp(481).

ron or roff was not set. Using phi to calculate. Step changes in demand rates as a function of time will be ignored.

• Ideally, in the method currently being used, ron and roff (heating and cooling rates) should be used to calculate phi. If you receive this error, the phi is being used to calculate ron and roff initially. However, phi does not update ron and roff at each time step, so you will not be able to perform disturbances of demand. If you wish this, please use ron and roff as a function of time instead. This can also be caused by using a schedule or player transform to describe the ron or roff values - essentially during the initialization, the value is not described yet. There is no current fix for this, but can be "faked" by setting phi to the correct initial value and waiting a couple of timesteps for things to settle. See residential/zipload.cpp(206).

Shunt capacitance of overhead line:'string' not calculated - invalid values

• While attempting to calculate the shunt capacitance for an overhead line, an invalid parameter was encountered. To calculate shunt capacitance, ensure the condutor to earth distance for each phase is defined, as well as the diameter of that phases's cable. See powerflow/overhead_line.cpp(496).

Solar object:'string' is in player mode - be sure to specify relevant values

• The solar array object is in player mode. It will not take values from climate files or objects. Be sure to specify the Insolation, ambient_temperature, and wind_speed values as necessary. It also will not incorporate any tilt functionality, since the Insolation value is expected to already include this adjustment. See generators/solar.cpp(489).

solar:'integer' 'string' - Deltamode is enabled for the module, but not this solar array!

• The solar array is not flagged for deltamode operations, yet deltamode simulations are enabled for the overall system. When deltamode triggers, this array may no longer contribute to the system, until event-driven mode resumes. This could cause issues with the simulation. It is recommended all objects that support deltamode enable it. See generators/solar.cpp(936).

solar:'string' - Default solar position model is not recommended for southern hemisphere!

• The Liu-Jordan (default) solar position and tilt model was built around the northern hemisphere. As such, operating in the southern hemisphere does not provide completely accurate results. They are close, but tilted surfaces are not properly accounted for. It is recommended that the SOLAR_TILT_MODEL SOLPOS be used for southern hemisphere operations. See generators/solar.cpp(449).

solar:'string' indicates it wants to run deltamode, but the module-level flag is not set!

• The solar object has the deltamode_inclusive flag set, but not the module-level enable_subsecond_models flag. The generator will not simulate any dynamics this way. See generators/solar.cpp(898).

solarpanel: 'integer' climates found, using first one defined

• More than one climate object was found, so only the first one will be used by the solar array object See generators/solar.cpp(267).

solarpanel: no climate data found, using static data

• No climate object was found and player mode was not enabled, so the solar array object is utilizing default values for all relevant weather variables. See generators/solar.cpp(285).

stored_capacity and SOC are both defined, SOC being used for initial energy state

• During the initialization of the system, a value was specified for both the stored_capacity and SOC (state of charge). The thermal energy storage object gives precedence to the SOC variable, so the initial stored_capacity will be the SOC percentage of the total_capacity. See residential/thermal_storage.cpp(246).

substation attached to pw_load and not a SWING bus - forcing to SWING

• When a substation object is connected to PowerWorld via a pw_load object, the substation must be designated as a SWING bus. This designation will now be forced upon the bus. See powerflow/substation.cpp(211).

substation is not a SWING bus, so answers may be unexpected

• A substation object appears set to accept sequence voltage values, but it is not a SWING bus. This may end up causing the voltages to be converted from sequence, but then overridden by the distribution powerflow solver. See powerflow/substation.cpp(236).

substation:'string' is set up as a normal node, no sequence values will be calculated

• A substation is currently behaving just like a normal powerflow node. If it was desired that it convert a schedule or player of sequence values, please initialize those values to non-zero along with the player attachment. See powerflow/substation.cpp(252).

SWING bus:'string' is not flagged for deltamode

• Deltamode is enabled for the overall powerflow module, but not for the SWING node of the powerflow. This means the overall powerflow is not being calculated or included in any deltamode calculations. If this is not a desired run method, please enable the deltamode_inclusive flag on the SWING node. See powerflow/node.cpp(1681).

switch objects may not behave properly under FBS!

• Due to the nature of the forward-backward sweep algorithm, and open switch may induce the desired behavior on the system. If open, it should prevent current flow and set the "to" end voltage to zero. However, this may cause problems in many powerflow conditions or not properly solve. Consider using the Newton-Raphson solver in conjunction with the reliability package, or rearrange your system. See powerflow/switch_object.cpp(143).

Switch status updated, but no other changes made.

• When changed under solver methods other than NR, only the switch status is changed. The solver handles other details in a specific step, so no other changes are performed. See powerflow/switch_object.cpp(1468).

Switch:'string' switch_resistance has been set to zero. This will result singular matrix. Setting to the global default.

• Under Newton-Raphson solution method the impedance matrix cannot be a singular matrix for the inversion process. Change the value of switch_resistance to something small but larger that zero. See powerflow/switch_object.cpp(168).

The dc voltage is greater than the specified maximum for the inverter. Efficiency model may be inaccurate.

• The DC voltage at the input to the inverter is less than the maximum voltage supported by the inverter. As a result, the multipoint efficiency model may not provide a proper result. See generators/inverter.cpp(3016).
• The DC voltage at the input to the inverter is less than the maximum voltage supported by the inverter. As a result, the multipoint efficiency model may not provide a proper result. See generators/inverter.cpp(3118).
• The DC voltage at the input to the inverter is less than the maximum voltage supported by the inverter. As a result, the multipoint efficiency model may not provide a proper result. See generators/inverter.cpp(7600).

The external solver solver_'string' could not be found, defaulting to superLU

• While attempting to link an external LU matrix solver library, the file could not be found. Ensure it is in the proper GridLAB-D folder and is named correctly. If the error persists, please submit your code and a bug report via the trac website. See powerflow/node.cpp(917).

The generator has already exhausted its yearly runtime quota, it will not run this year

• The value specified for current_year_runtime is larger or equal to yearly_runtime_limit. This means the generator has exhausted all of its available runtime hours for the year and will no longer run. See market/generator_controller.cpp(528).

The PV is over rated for its parent inverter.

• The maximum output for the PV array is larger than the inverter rating. Ensure this was done intentionally. If not, please correct your values and try again. See generators/solar.cpp(788).

This connection type on transformer:'integer' ('string') does not support impedance (impedance1 or impedance2) of secondaries at this time.

• At this time impedance1 and impedance2 are only defined and used for center-tap transformers to be explicitly defined. These values will be ignored for now. See powerflow/transformer_configuration.cpp(221).

This connection type on transformer:'integer' ('string') does not support shunt_impedance at this time.

• At this time shunt_impedance is only defined and supported in center-tap and WYE-WYE transformers. Theses values will be ignored for now. See powerflow/transformer_configuration.cpp(229).
• At this time no_load_loss and full_load_loss are only defined and supported in center-tap transformers. Theses values will be ignored for now. See powerflow/transformer_configuration.cpp(236).

transformer:'integer' 'string' is set to model saturation, but has no magnetization location

• While attempting to initialize a transformer for inrush saturation calculations, it was noticed that no magentization location was specified. No saturation can be modeled in this case. Please specify a winding to include the magnetization on with the magnetization_location of the transformer_configuration object. See powerflow/transformer.cpp(1757).

transformer:'string' is at 'real'%% of its rated power value

• The total power passing through a transformer is above its kVA rating. See powerflow/link.cpp(2960).

transormer_configuration:'integer' ('string') reactance_resistance_ratio was not set and defaulted to 4.5. This may cause issues with larger transformers (>0.5 MVA)

• X/R ratios are highly dependent on the size of the transformer. As the transformer rating goes up so does the X/R ratio. For small residential transformers (<500 kVA), the values range from about 2-5 as good estimates. For a good X/R reference, recommend GE's GET-3550F document, Appendix Part II. See powerflow/transformer_configuration.cpp(248).

triplex_load:'string' - constant_current loads in deltamode are handled slightly different

• Due to the potential for moving reference frame of deltamode systems, constant current loads are computed using a scaled per-unit approach, rather than the fixed constant_current value. You may get results that differ from traditional GridLAB-D super-second or static powerflow results in this mode. See powerflow/triplex_load.cpp(155).

Unable to compute capacitance for 'string'

• One phase of an underground line has either a conductor diameter, a concentric-neutral location diameter, or a neutral strand count of zero. This will lead to indeterminant values in the analysis. Please fix these values, or run the simulation with line capacitance disabled. See powerflow/underground_line.cpp(823).
• One phase of an underground line has either a conductor diameter, a concentric-neutral location diameter, or a neutral strand count of zero. This will lead to indeterminant values in the analysis. Please fix these values, or run the simulation with line capacitance disabled. See powerflow/underground_line.cpp(950).

Unable to find secondary interruption flag, no secondary interruptions recorded in metrics:'string'

• While attempting to link to the 'secondary customer interrupted' flag, it was not found. THe object may not support "secondary interruption counts" and this message is valid. If a secondary count was desired, ensure the object supports being polled by reliability as a customer (customer_interrupted_secondary exists as a published property) and try again. If the error persists, please submit your code and a bug report via the trac website. See reliability/metrics.cpp(464).

Unable to map add_event function in eventgen:'string'

• While attempting to map the "add_event" function from an eventgen object, the function failed to be found. Ensure the target object in fault_check is an eventgen object and this function exists. If the error persists, please submit your code and a bug report via the trac website. See powerflow/fuse.cpp(341).
• While attempting to map the "add_event" function from an eventgen object, the function failed to be found. Ensure the target object in fault_check is an eventgen object and this function exists. If the error persists, please submit your code and a bug report via the trac website. See powerflow/switch_object.cpp(714).

Unable to map mean_repair_time from object:'string'

• While attempting to access the mean_repair_time of the safety device, GridLAB-D encountered an error. Ensure the object has this value. If it does not, it will be ignored. If it does exist and this warning appeared, please try again. If the warning persists, please submit your code and a bug report via the trac website. See powerflow/link.cpp(7254).
• While attempting to access the mean_repair_time of the safety device, GridLAB-D encountered an error. Ensure the object has this value. If it does not, it will be ignored. If it does exist and this warning appeared, please try again. If the warning persists, please submit your code and a bug report via the trac website. See powerflow/link.cpp(10059).

Underground_line:'integer' 'string' - phase N conductor should just be a normal conductor!

• A conductor on phase N has properties that imply it is either a concentric neutral or a tape-shield cable. This is redundant for a neutral connection and may not be necessary. See powerflow/underground_line.cpp(1308).

Underground_line:'integer' - 'string' is a tape-shielded cable and may need an explicit phase N conductor

• The underground cable is set up as a tape-shielded cable. For neutral currents, it may require an explicit neutral to be connected, unless it represents a delta-connected system. See powerflow/underground_line.cpp(709).

Unsupported phase on a possibly meshed node

• An unsupported connection was found on the system. Since reliability is enabled, the solver will simply ignore the unsupported components for now. See powerflow/fault_check.cpp(357).

Unsupported phase on node 'string'

• An unsupported connection was found on the indicated bus in the system. Since reliability is enabled, the solver will simply ignore the unsupported components for now. See powerflow/fault_check.cpp(287).

Vehicle location not set, using defaults

• The value for vehicle_index was not set, so a read of the NHTS file was not even attempted. A set of default values will be used instead. See residential/evcharger_det.cpp(215).

VFD:'integer' - 'string' - FROM node nominal_voltage is not equal to or greater than TO node nominal_voltage - implies DC-DC converter!e

• The from node nominal_voltage is less than the to node nominal_voltage. This implies an internal DC-DC converter, which is not explicityly modeled. Efficiency values will not be accurate! See powerflow/vfd.cpp(201).

VFD:'integer' - 'string' - nominal_output_frequency is not set or is negative - defaulting to system nominal

• The nominal_output_frequency variable was not set properly - defaulting to nominal_frequency of the system. See powerflow/vfd.cpp(211).

VFD:'integer' - 'string' - rated_output_voltage does not match the TO node nominal voltage

• The rated_output_voltage does not match the nominal_voltage of the TO node. This may cause some issues with simulations results. See powerflow/vfd.cpp(189).

VFD:'integer' - 'string' - rated_output_voltage was not set, defaulting to TO node nominal

• The rated_output_voltage was not set for the VFD. It has been defaulted to the nominal_voltage value of the TO node. See powerflow/vfd.cpp(174).

VFD:'integer' - 'string' - the desired_motor_speed results in a frequency of less than 3.0 Hz

• The desired_motor_speed results in a value that is less than the starting frequency of a typical VFD. This is high discouraged, since it may not function properly in this range. See powerflow/vfd.cpp(367).

VFD:'integer' - 'string' - VFD currently at 'real'%% of rated speed -- VFDs perform best when running at >= 75 percent output

• Recommended to run a VFD at 75%. Lower values are not recommended and can result in odd behavior See powerflow/vfd.cpp(376).

volt_var_control 'string': A link to monitor power-factor was not specified, using first regulator.

• The volt_var_control object requires a link-based object to measure power factor. Since one was not specified, the control scheme will just monitor the power values of the first feeder regulator. See powerflow/volt_var_control.cpp(809).

volt_var_control 'string': capacitor_delay should be greater than or equal to 1 to prevent convergence issues.

• The capacitor_delay should be greater than or equal to 1.0 to avoid having a system oscillate switch positions until the convergence limit is reached. See powerflow/volt_var_control.cpp(211).

volt_var_control 'string': Desired, minimum, and maximum voltages don't match

• The lists for desired_voltages, minimum_voltages, and maximum_voltages should all have the same number of elements. If they don't, if at each field has at least one specification, the first for each will be used on all regulators. If they don't all have at least one specification, the whole set will be set to default values. See powerflow/volt_var_control.cpp(549).

volt_var_control 'string': Low loading deadband for regulator 'integer' is expected to be larger than the high loading deadband

• The high_load_deadband is larger than the low_load_deadband setting. The algorithm proposed in the referenced paper suggests low_load_deadband should be larger (less constrained) than the high load. This may need to be fixed to be consistent with expected results. See powerflow/volt_var_control.cpp(771).

volt_var_control 'string': No capacitors specified.

• The capacitor_list in the volt_var_control is empty. This means no capacitors are controlled by the volt_var_control object, which more or less means you have voltage setpoint regulators and no need for a central control. See powerflow/volt_var_control.cpp(1126).

volt_var_control 'string': No measurement point specified for reg 'integer' - defaulting to load side of regulator

• If no measuremnt points are specified for a regualtor in the volt_var_control object, it will default to the load side of the regulator. Please specify measurement points for better control. See powerflow/volt_var_control.cpp(1418).

volt_var_control 'string': Power factor monitored phases not set - defaulting to substation_link phases

• The pf_phases variable was not set, so the volt_var_control object defaulted to the phases of the substation_link object. If this is not desired, please specify the phases on pf_phases. See powerflow/volt_var_control.cpp(1503).

volt_var_control 'string': regulator_delay should be greater than or equal to 1 to prevent convergence issues.

• The regulator_delay should be greater than or equal to 1.0 to avoid having a system oscillate switch positions until the convergence limit is reached. See powerflow/volt_var_control.cpp(228).

volt_var_control 'string': The set point for phase A will exceed the maximum allowed voltage!

• The set point necessary to maintain the end point voltage exceeds the maximum voltage limit specified by the system. Either increase this maximum_voltage limit, or configure your system differently. See powerflow/volt_var_control.cpp(1713).

volt_var_control 'string': The set point for phase A will exceed the minimum allowed voltage!

• The set point necessary to maintain the end point voltage exceeds the minimum voltage limit specified by the system. Either decrease this minimum_voltage limit, or configure your system differently. See powerflow/volt_var_control.cpp(1737).

volt_var_control 'string': VDrop, low V BW, and high V BW don't match

• The lists for maximum voltage drop, voltage drop low loading, and voltage drop high loading should all have the same number of elements. If they don't, if at each field has at least one specification, the first for each will be used on all regulators. If they don't all have at least one specification, the whole set will be set to default values. See powerflow/volt_var_control.cpp(657).

waterheater:'integer' is boiling

• The temperature model for the waterheater has broken, or the environment around the waterheater has burst into flames. Please post this with your model and dump files attached to the bug report. See residential/waterheater.cpp(679).

windturb_dg (id:'integer', name:'string'): Rated generator voltage (LL: 'real') and nominal voltage (LL: 'real') of meter parent are different by greater than 10 percent. Odd behavior may occur.

• Currently, the model allows you to attach the turbine to a voltage that is quite different than the rated terminal voltage of the generator. However, this may cause odd behavior, as the solved powerflow voltage is used to calculate the generator induced voltages and conversion from mechanical power. It is recommended that the nominal voltages of the parent meter be within ~10% of the rated voltage. See generators/windturb_dg.cpp(541).

windturb_dg (id:'integer',name:'string'): internal iteration limit reached, breaking out of loop. Injected current may not be solved sufficiently.

• This may need some work. The generator models are solved iteratively by using the system voltage as the boundary condition. The current model iterates on solving the current injection, but then breaks out if not solved within 100 iterations. May indicate some issues with the model (i.e., voltage is incorrectly set on the connection node) or it may indicate poor programming. Please report if you see this message. See generators/windturb_dg.cpp(931).

zipload_init: The demand response zipload is an experimental model at this time.

• The warning is pretty obvious. However, over time, we will be developing this model further. If you have any questions about it, please see the Matlab files found in ../design/dr_model/ or read the paper titled "On the Equilibrium Dynamics of Demand Response" submitted to HICSS 2011 or post your questions on the WIKI forum. See residential/zipload.cpp(142).

zipload_init: Using a value for thermostatic_control_range (L) greater than 50 may cause some instabilities.

• This warning is shown only as a reminder. Large values of L (thermostatic_control_range) can cause instabilities for some combinations of ron and roff. If you receive inderminant numbers as part of the solution, try reducing L. See residential/zipload.cpp(173).

• The indicated sync function is not implemented by the class given. This happens when the PASSCONFIG flag indicates a particular sync (presync/sync/postsync) needs to be called, but the class does not actually implement it. This is a problem with the module that implements the class. See gldcore/object.c(1433).

ordinal 'integer' is too small (first is 'integer')

• This is an internal error caused by an attempt to index something improperly. Because the indexing system start at index 0, this means a negative index number was attempting, which is most likely a bug. This usually occurs during object initialization and might be caused by invalid object numbers, either negative or greater than about 2 billion. If your model is using a the class:id naming convention, check the object id numbers to make sure they are correct. See gldcore/index.c(76).

• The powerflow solver has detected that a nominal voltage was not specified or is invalid. Specify this voltage as a positive value via nominal_voltage to enable the solver to work. See powerflow/node.cpp(1109).

object 'string' commit failed

• The commit function of the named object has failed. Make sure that the object's requirements for committing are satisfied and try again. (likely internal state aberations) See gldcore/exec.c(1107).

object_close_namespace(): no current namespace to close

• An attempt to close a namespace was made while there was no open namespace. This is an internal error and should be reported. See gldcore/object.c(2516).

object_create_foreign(OBJECT *obj=): obj->oclass is not really a class

• An attempt to create an object was given a class that most likely is not a class. This is most likely a bug and should be reported. See gldcore/object.c(392).

object_create_foreign(OBJECT *obj=): object->oclass is NULL

• The system has run out of memory and is unable to create the object requested. Try freeing up system memory and try again. See gldcore/object.c(385).

object_create_foreign(OBJECT *obj=NULL): object is NULL

• An attempt to create an object was given a NULL pointer for the class. This is most likely a bug and should be reported. See gldcore/object.c(377).

object_create_single(CLASS *oclass='string'): abstract class 'string' cannot be instantiated

• An attempt to create an object using an abstract class was detected. Some classes may only be inherited but cannot be used directly in models. See gldcore/object.c(308).

object_create_single(CLASS *oclass='string'): memory allocation failed

• The system has run out of memory and is unable to create the object requested. Try freeing up system memory and try again. See gldcore/object.c(318).

object_create_single(CLASS *oclass=NULL): class is NULL

• An attempt to create an object was given a NULL pointer for the class. This is most likely a bug and should be reported. See gldcore/object.c(300).

object_dump(char *buffer=%x, int size='integer', OBJECT *obj='string':'integer') buffer overrun

• The buffer used to dump objects has overflowed. This can only be fixed by increasing the size of the buffer and recompiling. If you do not have access to source code, please report this problem so that it can be corrected in the next build. See gldcore/object.c(1687).
• The buffer used to dump objects has overflowed. This can only be fixed by increasing the size of the buffer and recompiling. If you do not have access to source code, please report this problem so that it can be corrected in the next build. See gldcore/object.c(1704).

object_open_namespace(char *space='string'): memory allocation failure

• The memory required to create the indicated namespace is not available. Try freeing up system memory and try again. See gldcore/object.c(2497).

print_class_d: tabdepth > 32, which is mightily deep!

• This means that there is very deep nesting and this is unexpected. This suggests a problem with the internal model and should be reported. See gldcore/cmdarg.c(110).

property 'string' not found in object 'string'

• The property for which the unit was requested does not exist. Depending on where this occurs it's either a bug or an error in the model. Try fixing your model and try again. If the problem persists, report it. See gldcore/object.c(257).

property_malloc(oclass='string',...): property 'string' unit 'string' is not recognized

• A class is attempting to publish a variable using a unit that is not defined. This is caused by an incorrect unit specification in a variable publication (in C++) or declaration (in GLM). Units are defined in the unit file located in the GridLAB-D etc folder. See gldcore/property.c(151).

random_exponential(l='real'): l must be greater than 0

• An attempt to generate a random number used a parameter that was outside the expected range of real numbers. Correct the functional definition of the random number and try again. See gldcore/random.c(473).

random_pareto(m='real', k='real'): k must be greater than 1

• An attempt to generate a random number used a parameter that was outside the expected range of real numbers. Correct the functional definition of the random number and try again. See gldcore/random.c(435).

random_sampled(n='integer',...): n must be a positive number

• An attempt to generate a random number used a parameter that was outside the expected range of real numbers. Correct the functional definition of the random number and try again. See gldcore/random.c(397).

random_weibull(l='real', k='real'): k must be greater than 0

• An attempt to generate a random number used a parameter that was outside the expected range of real numbers. Correct the functional definition of the random number and try again. See gldcore/random.c(504).

raw unit 'string' was not found

• The requested unit was not found by the unit subsystem. There is a good chance that this function will end up triggering a null pointer exception if not properly handled. See gldcore/unit.c(230).
