The power system test cases on this page are non-confidential and are provided in a variety of different formats, including PowerWorld Simulator and PowerWorld DS (*.pwb, *.pwd, *.tsb, *.aux), Matpower (*.m), PSSE (*.raw, *.dyr), and PSLF (*.epc, *.dyd).
Synthetic Electric Grid Cases
Synthetic electric grid models are fictitious representations that are designed to be statistically and functionally similar to actual electric grids while containing no confidential critical energy infrastructure information (CEII). Some of these cases were developed with the support of the U.S. DOE ARPA-E Grid Data program; their support is gratefully acknowledged.
Description of the algorithms used to develop the cases, models, and time series are given in:
