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. A description of the initial algorithm used to develop these cases is given in:
A. B. Birchfield; T. Xu; K. M. Gegner; K. S. Shetye; T. J. Overbye, “Grid Structural Characteristics as Validation Criteria for Synthetic Networks,” in IEEE Transactions on Power Systems, vol. 32, no. 4, pp. 3258-3265, July 2017.
When using these models please cite this paper. A complete list of papers describing how the synthetic models were created is included here.

All cases displayed above include a feasible AC power flow solution. Icons next to each case indicate whether additional parameters/models are included: TS for transient stability, GMD for geomagnetic disturbance analysis, OPF for energy economic study, PWDS for PowerWorld Dynamic Studio scenarios, MOV if case movies are available and PMU if synthetic PMU data is available.
Here are some introductory videos showing how these interactive power system simulation cases improve the situational awareness of current system operating conditions.
