About the test cases library
This website provides a power system oscillation test cases library including both simulated cases and actual oscillatory events in power systems. The main objective for this library is to facilitate the development and testing of algorithms, methods and tools for identifying the source of poorly damped or forced oscillation in power systems.
All simulated cases were created by simulation on a WECC 179-bus power system model (click to see description on the WECC 179-bus system base case model). With each test case of the library, we provide a case description, simulation results (to mimic PMU measurements with oscillation), and the simulation model in the PSS/E V30 format.
Cases of actual oscillatory events are provided as the sets of actual PMU measurements collected from multiple points of actual power systems during oscillatory events. Each case is supplied with a description.
The development of this test cases library was led by Dr. Slava Maslennikov (ISO-NE). The website is maintained by Mr. Xin Xu (UTK) and Dr. Kai Sun (UTK). Related simulation models and Matlab codes were prepared by Dr. Bin Wang. Currently, there are 5 actual oscillation events and 27 simulated oscillation cases (including 9 cases on poorly damped natural electromechanical oscillations and 18 cases on forced oscillations). More cases will be added on an as-needed basis.
