Design of PID Controller for Power System Stabilization Using Hybrid Particle Swarm-Bacteria Foraging Optimization
Authors: , ,
Abstract: This paper considers the stabilization of a synchronous machine connected to an infinite bus via a PID. The PID parameters are tuned using hybrid Particle Swarm-Bacteria Foraging Optimization (PSO-BFA). Simulation results are introduced with and without the proposed controller. Also, a comparison study is introduced when using classical PID, only bacteria foraging optimization and when using hybrid particle swarm- bacteria foraging optimization. The results show that using of hybrid control is capable of guaranteeing the stability and performance of the power system better than the PID-PSS based classical PID and BFA only.
