Particle Swarm Optimization (PSO) based 2-DoF-PID power system stabilizer design for damping out low frequency oscillations in power systems

Abstract

Low frequency oscillation (LOF) could be a serious concern in grid. It may occur due to tiny signal perturbation. It will cause complete grid collapse. Power system stabilizer (PSS) is used to help the system by rising the damping of grid. During this paper, particle swarm optimization (PSO) based two-degree of freedom PID stabilizer is planned to enhance the damping of the system. The stabilizer parameters are tuned utilizing PSO. Integral square error (ISE) is picked as the objective criterion for the plan. To execute this, IEEE type DC1 exciter with single machine unbounded bus (SMUB) system is considered. The execution of the PSO based 2-DoF-PID is compared with PSO based PI, PID stabilizers. To check the viability of the structured stabilizers, comparatives investigation is finished with some current outcomes.
