The Electric Grid Test Case Repository is hosted by Prof. Thomas Overbye , Department of Electrical and Computer Engineering in the College of Engineering at Texas A&M University with support of ARPA-E's GRID DATA program.
Synthetic electric grid cases are a representation of power grids with a detailed modeling of the power system dynamics and protections. Works  –  present a methodology to create entirely fictitious synthetic power system networks that can capture structural and functional characteristics of actual power grids. Synthetic network base cases are extended with generator cost data and dynamic models for energy economic and transient stability studies in works  and , respectively.
Synthetic networks have no relation to the actual electric grid in their geographic location, thus they contain no confidential information and pose no security concern. Researchers can freely use synthetic power grid to test and validate new tools and techniques as on actual power grid.
