This webpage is intended to provide a repository of publicly available, non-confidential power flow and/or transient stability cases. These cases are available in a variety of different formats, including PowerWorld Simulator (*.pwb, *.pwd, *.aux), Siemens PTI PSS/E (*.raw, *.dyr), and GE PSLF (*.epc, *.dyd).
All cases include a power flow. Icons next to each case indicate whether additional parameters are included. These are TS for transient stability, GMD for geomagnetic disturbance analysis, PWDS for PowerWorld Dynamic Studio scenarios and MOV if case movies are available.
If you would like to contribute additional cases, please email them to Prosper Panumpabi at email@example.com in one of those formats; include a brief description of the case.
