Abstract:Simulation of the transient stability problem of a power system, which is the assessment of the short term angular and voltage stability of the system following a disturbance, is of vital importance. 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. The goal of this work is to develop validation methodologies for different transient stability software packages with a focus on Western Electricity Coordinating Council (WECC) system models. We discuss two specific approaches developed and implemented to validate the transient stability results. The sources of discrepancies seen in the results from different packages are investigated. This enables us to identify the differences in the implementation of dynamic models in different transient stability softwares. In this process, we present certain key analyses of the WECC system models for different contingencies.
