TCSC $H{\infty}$ Controller Design for Damping Interarea Oscillations

지역간 진동모드 제동을 위한 $H{\infty}$-TCSC 최적 제어기 설계

The design of an $H{\infty}$ controller for a TCSC to enhance the damping of an inter-area oscillation in a Power system is presented. The paper describes a comprehensive and systematic way of applying the $H{\infty}$ control design algorithm in power systems. Eigen sensitivity analysis to selction a TCSC location is described. Time simulation and eigenvalue analysis show that the proposed TCSC $H{\infty}$ controller can suppress the inter-area oscillations efficiently with robustness.
