Abstract
This chapter presents an algorithm to design a decentralized robust controller for STATCOMs (static synchronous compensators) using minimax linear quadratic (LQ) output-feedback control design approach. There is an increase of the available (dynamic) transfer capability (ATC) of power systems with fixed-speed wind generators (FSWGs) due to the designed decentralized controllers. The effects of the integration of various types of wind generators into power systems based on transfer limit has also been analyzed in this chapter. The effectiveness of the suggested control strategy is validated by simulations on a benchmark two area power system. The performance of the designed controller is also compared with a conventional PI (proportional-integral)-based STATCOM controller. Simulation results show that both the dynamic voltage stability and the transient stability can be improved by the use of the robust STATCOM control presented in this chapter.
