Wide area controller design of STATCOM and PSS in Multimachine power system using BF-PSO Algorithm

In this paper, an optimal wide area controller is designed for a multi-machine power system together with a Static Compensator (STATCOM). Wide area control signals are usedto provide auxiliary control to power system stabilizers (PSS) and STATCOM in order to achieve enhanced damping of systemoscillations in power systems. A modified intelligent Particle Swarm Optimization (BF-PSO) has been used for optimal andcoordinated selection of the STATCOM and Power SystemStabilizers (PSS) of generators wide area damping controller parameters. Then, Simulation results are provided in a sample ٤-machine ١٠-bus (Kundur) power system to indicate that the proposed wide area controller improves the damping of the rotorspeed deviations of the generators during large scale disturbances. Simulation results have shown that the proposedcoordinated wide area controller using modified BF-PSO canreach to optimal and coordinated selection of the STATCOM and PSS damping controller parameters accurately and has better performance in damping oscillations
