Validation of real-time system model in western interconnection

In order to implement the real-time Transient Security Assessment Tool (TSAT) for overall Interconnection, Peak Reliability (West Electricity Coordination Council (WECC) Reliability Coordinators) has linked the West-wide System Model (WSM) with WECC dynamic database library. To make sure that model and application are trustworthy for control room implementation, model validation studies are performed by simulating multiple historical events. The simulation results are compared to the Phasor Measurement Units (PMU) and SCADA recordings. This paper shows some validation results and proposes a standard procedure that could be useful for future validation studies on other real-time operational models.
