GridLAB-D is an open-source (BSD license) simulation and analysis tool that models emerging smart grid energy technologies.
GridLAB-D was developed with funding from the US DOE Office of Electricity (OE) at Pacific Northwest National Laboratory (PNNL), in collaboration with industry and academia.
In 2017 the CEC awarded several grants[4] to enhance GridLAB-D with the aim to support use in California regions operated by the investor-owned utility ratepayers.
The enhancements focus on the California Public Utilities Commission's (CPUC) proceedings related to distributed and renewable energy resource integration, with particular attention to usability, scalability and interoperability.
Hitachi America Laboratory (HAL) leads the GridLAB-D Open Workspace (GLOW)[5] project to develop a user-interface for GridLAB-D. SLAC National Accelerator Laboratory (SLAC) leads the High-Performance Agent-based Simulation (HiPAS)[6] project to enhance the performance of GridLAB-D. HiPAS GridLAB-D is released through GitHub.
