A test cases library for methods locating the sources of sustained oscillations

A test cases library is created to provide a common foundation to test methods for locating the source of a poorly damped or forced oscillation by using wide-area measurements. The library is built on a simplified WECC 179-bus system and includes both poorly damped and forced oscillation cases. Three source locating methods were fully tested using the library, and two selected cases for each method are presented in this paper to demonstrate the advantages and the disadvantages of each method. This library would help validate, evaluate and improve methods locating the oscillation sources in power systems.
