The next revolution in power systems simulation

Today's power systems simulation tools don't provide the analysis capabilities needed to study the forces driving change in the energy industry. The combined influence of fast-changing information technology, novel and cost-effective distributed energy resources (DER), multiple and overlapping energy markets and new business strategies result in high uncertainty about the success of these important innovations.

GridLAB-D™ — A unique tool to design the smart grid

GridLAB-D is a first-of-its-kind time-series power distribution system simulation and analysis tool that provides valuable information to users who design and operate distribution systems, and to utilities that wish to take advantage of the latest energy technologies. It incorporates advanced modeling techniques with high-performance algorithms to deliver the latest in end-use load modeling technology. Historically, the inability to effectively model and evaluate smart grid technologies has been a barrier to adoption; GridLAB-D is designed to address this problem.

GridLAB-D was developed by PNNL in collaboration with industry and academia through funding from the U.S. Department of Energy Office of Electricity Delivery and Energy Reliability (DOE/OE). GridLAB-D is designed as an open-source tool, freely available to any user, to encourage collaboration with industry and academia. The BSD-style license allows vendors to add or extract their own modules without exposing internal intellectual property. An important capability in PNNL's EIOC, GridLAB-D incorporates the most advanced modeling techniques with high-performance algorithms to deliver the best in end-use modeling.

GridLAB-D is a flexible, agent-based simulation environment designed to model not only the power system, but the overlying systems that affect the power system. At its simplest, GridLAB-D examines the detailed interplay between all elements of a distribution system from the substation to end-use load. GridLAB-D provides a valuable test bed for evaluating control strategies and cost-to-benefits ratios. It provides a sand box for studying the effects of smart grid technologies without the cost and complexity of field demonstrations.
