Stability of Series Capacitor Compensated Thermal Power System with FSWTGs under Strong Wind Gust

Abstract

This paper studies the effect of a strong wind gust on the stability of a series capacitor compensated thermal power system with Fixed Speed Wind Turbine Generators (FSWTGs). The IEEE first benchmark model (IEEE-FBM) for Subsynchronous Resonance (SSR) studies has been adopted and modified to perform the study. The influence of the strong wind gust on the stability of the system is investigated at different degrees of series compensation and power rating of the FSWTGs. Time domain simulations using PSCAD are employed to perform the study. Simulation results showed that strong wind gusts can cause instability in the system.
