Bacterial foraging optimization algorithm used to adjust the parameters of Power System Stabilizers and Thyristor Controlled Series Capacitor-Power Oscillation Damping controller

Abstract

The objective of this paper was to use the Bacterial Foraging Optimization algorithm to determine the parameters of Power System Stabilizers and a Thyristor Controlled Series Capacitor-Power Oscillation Damping controller. The proposal is to synchronize adjustments of these controllers in order to introduce the desired low frequency oscillation damping in an electric power system. A test system distributed in two areas with 4 generators, 10 bus and 15 transmission lines and with local and inter-area oscillation modes is simulated to test the design. The results demonstrate the ability of the algorithm to achieve the objectives defined in this paper.
