Adjustment of PSS in a multi machine power system based on particle swarm optimization technique


The tuning of the PSS parameters for a multi-machine power system is usually formulated as an objective function with constraints consisting of the damping factor and damping ratio. A novel Meta heuristic optimization method, called particle swarm optimization method (PSO), is proposed to solve this kind of problem. An objective function based on the integral of the error is incorporated. The IEEE 14 bus standard power system, under various system configurations, is employed to illustrate the performance of the proposed method. Nonlinear time domain simulation results demonstrate the effectiveness of the proposed algorithm and the objective function with a remote signal.
