Validation and Accreditation of Transient Stability Results

Description Simulation of the transient stability problem, which is the assessment of the short term (several to 30 seconds) angular and voltage stability of the power system following a disturbance, is of vital importance. For some portions of the North American power grids, such as the Western Electric Coordinating Council (WECC), transient stability has always been an important consideration, while for other portions it is of growing concern due partially to the widespread integration of wind generation. It is widely known in the industry that different transient stability packages can give substantially different results for the same (or at least similar) system models. This presentation presents results from a PSERC project that investigated the source of these differences. The presentation will also provide a discussion of transient stability validation methodologies.
