Computationally Fast Particle Swarm Optimization Power System Stabilizer Design for Interconnected Multimachine Power System

In this paper, for multi-machine power system, computationally fast binary particle swarm optimization (BPSO) based power system stabilizer design is presented. It is necessary to make the best setting of PSS (Power System Stabilizer) parameters for improving its contribution towards the damping oscillation with less computational time for solving the PSO programming. The result shows the performance of PSS in a multi-machine environment for a proposed objective function. Time-domain simulation results of the PSO based PSS under different operating conditions are demonstrated on the 16-machine, 68-bus system.
