HiPAS GridLAB-D

GridLAB-D is a research simulator developed by the US Department of Energy and used to study future electricity distribution systems. HiPAS GridLAB-D is a commercial-grade high-performance version of this software developed for four California use-cases: load electrification, distributed resource integration hosting capacity, tariff design, and distribution system resilience. These use-cases address California’s climate change goals, including electricity infrastructure decarbonization and response to climate change impacts on electricity distribution system infrastructure.

HiPAS GridLAB-D was released as Arras Energy as an open-source product available from the Linux Foundation (LF) Energy project. It is available free-of-charge for users, and easily installed on the most widely used computing platforms. Software support and maintenance infrastructure is open to contributors and administered by professional software engineers in consultation with experienced electrical and mechanical engineers. 

Key results:

●        Achievement of 97.5% success rate in automatic conversion from Cyme models.

●        Simulation speed tests approximately 180 times faster than the DOE version of GridLAB-D.

●        Significant reductions in cloud operating costs, including 94% reduction in storage, and more than 99% reductions in runtime and computing costs. 

LF Energy is an open-source foundation focused on the power systems sector. LF Energy adopted HiPAS GridLAB-D and hosts it within the Linux Foundation’s neutral, collaborative community to build the shared digital investments that are transforming the world's relationship to energy.
