Title

Simultaneous Design of Power System Stabilizers for the Nigeria Power System Using Bacteria Foraging

Abstract

The basic intent of adding Power System Stabilizers (PSSs) is to enhance system damping and power transfer limits. The PSS with the excitation system of a synchronous machine modifies the torque angle of the shaft to increase damping. In this paper, Bacterial Foraging Algorithm (BFA) is presented for the design of optimal PSSs. The BFA is used to determine the optimal parameters of multiple PSSs simultaneously for the Nigerian power system. Optimal PSS parameters are determined for the power system subjected to small and large disturbances. The effectiveness of the PSS parameters determined by the BFA is observed in damping out the power system oscillations after a disturbance. The advantage of the proposed approach is presented in this paper.
