GridLAB-D™ Demonstrations

GridLAB-D™ is flexible, agent-based simulation engine that allows users to explore a wide variety of analyses or even constructing new scenarios during runtime. However, the complexity of GridLAB-D™ can sometimes be intimidating during the initial learning stages. This interactive, web-based tool was created through a series of education projects to introduce new users to some of the complexities of distribution systems, while simplifying the interaction with the underlying tool, GridLAB-D™.

Feel free to use this web-interface as means to explore some of the capabilities of GridLAB-D™. Please be aware that some of the models may take a few minutes to simulate. Once they have been simulated previously, they will be stored on the server and will be quickly accessible.

A quick introduction to what you will see:

Voltage Control

    This explores traditional voltage control on a distribution system, including regulator and capacitor operational set points. Users will be able to modify a wide variety of these parameters, including control types, sensing locations, and time delays.


    This explores the effects of photovoltaic and inverter penetration on a traditionally operated system, including the effects on overloading, voltage control, and losses across a variety of weather patterns. Users will be able to change the solar penetration level and weather types.

Energy Storage

    This explores the effects of a small system with a battery charging system designed to offset the load at a transformer (i.e., peak shaving) with nine residential customers. Users will be able to modify the size of the battery and the charge and discharge setpoints.

Solar Demonstration Simulation

    This is a demonstration of the effects of "cloud transients" on a simple distribution system with varying levels of photovoltaic penetration. This is purely a web-based demonstration with stored data and does not simulate new models.
