    Abstract

    Power system stabilizing control plays an important role to remain in synchronism during major disturbances resulting from sudden or sustained load changes. TCSC (Thyristor Controlled Series Capacitor) is one of the representative devices of FACTS (Flexible AC Transmission System). In this paper, a design method for output feedback TCSC controller using detailed model has been applied to suppress system disturbances in large-scale power systems. As the methodology of robust controller design, H control has been adopted. Currently, LMI (Linear Matrix Inequality) is very effective, since it solves the Lyapunov inequality without considering the weighting coefficients used in other control theories. In the proposed approach, the load change is treated as a system uncertainty in the LMI approach. The proposed LMI-based approach is proved to be applicable for the design of TCSC controllers to enhance robustness and response by simulations on a test system.
