摘要：To supply power demands reliably, power system should cope with various disturbances and faults and its stability should be retained. A power system may be failed due insufficient damping of synchronizing torque. In this paper, to improve the dynamic stability of a power system a feedback control based on H2 method is designed. To formulate the problem appropriately, linear matrix inequality (LMI) theory is employed. To optimize the overall closed-loop system response, the parameters of controller is optimized using particle swarm optimization (PSO) algorithm. Simulation results represent the effectiveness and validity of the proposed controller and its superiority over conventional power system stabilizer (PSS).
