ABSTRACT

With rapid increase in utilization of renewable energy systems, wind energy, in particular, satisfies the demand of electricity. However, the integration of wind energy system in an existing system that has a conventional turbine generator system, the level of series compensation will have a subsynchronous resonance (SSR) impact on either turbine generator system or wind turbine generators. This chapter outlines the importance of flexible alternating current transmission system (FACTS) devices, namely, static synchronous series compensator (SSSC) and thyristor-controlled series capacitor (TCSC) along with fuzzy-based controllers to damp or mitigate the SSR oscillations at a faster rate. A wind power integrated IEEE Second Benchmark Model (SBM) system is considered for the study. The system is tested with different series compensation levels under both steady-state and transient-state conditions. From the results, it is observed that fuzzy logic controller (FLC) SSSC can damp SSR oscillation at a faster rate even under different loaded conditions.
