چکیده
Static Synchronous Compensator (STATCOM) can improve power factor and dynamic stability on power system. STATCOM is Multiple Input and Multiple Output (MIMO) system, which can be presented by a mathematical model. This paper presents an application of Particle Swarm Optimization (PSO) as a modern tool to design controller parameter of weighting matrices Q and R of the LQ optimal control to obtain optimal gain as feedback of the Static Synchronous Compensator (STATCOM) in its optimization. The LQ optimal control is designed using PSO to improve the dynamic response of the Static Synchronous Compensator (STATCOM). The final result show that application of LQ optimal control designed by using PSO can suppress active current Id, reactive current Iq, and DC voltage Vdc in the shortest settling time among the application of the alternative of proposed control. Keywords STATCOM, linear quadratic (LQ) optimal control, particle swarm Optimization (PSO).
