Gridworks is partnering with Stanford National Accelerator Laboratory (SLAC), Hitachi, National Grid, and the Pacific Northwest National Lab (PNNL) leading three CEC EPIC projects to develop distribution system modeling tools to evaluate distributed energy resources.

Modeling software for power systems is undergoing significant development to address an increasingly complex electric grid. This initiative looks to address some of these most pressing needs by enhancing GridLAB-D, an open source distribution simulation and analysis modeling software developed by the U.S. Department of Energy. GridLAB-D is capable of dynamic analysis, estimation of the grid benefits and impacts of DERs, and support of decision making and planning processes on the distribution system.

This initiative looks to enhance GridLAB-D through three discrete projects, developing:

  1. An open source modeling framework and translation tool;
  2. High-performance computing in open source grid modeling; and
  3. An open source user interface for GridLAB-D.

Open Framework for Integrated Data Operations (OpenFIDO) is a data interchange, synthesis and analysis framework allowing interoperability between different power systems tools. This capability allows for a more reliable and efficient data exchange.

High-Performance Agent-Based Simulation using GridLAB-D (HiPAS GridLAB-D) is an open-source upgrade to GridLAB-D that speeds up the analysis performance and computational efficiency of the tool, using intelligent, adaptive multi-threading to deploy highly granular parallelization in agent-based simulations.

GridLAB-D Open Workspace (GLOW) looks to develop a high-end user interface for GridLAB-D that is more intuitive and user-friendly for all stakeholders, including non-expert users, to increase access to simulation and modeling results.

Next Meeting

Live Webinar Event – GLOW: An Open-source Distribution Planning Tool Based on GridLAB-D
This talk will provide the background policies, requirements, and use case related to DERs integration. We will present the current development of GridLAB-D Open Workspace (GLOW) which is an open source distribution planning platform based on GridLAB-D. With addition of a graphical user interface, GLOW provides a user-friendly environment for a stakeholder involved in deployment of DERs. We will demonstrate GLOW through a web-based UI on a cloud computing platform. This talk will also include the future development of GLOW for beta release in 2021.
