Abstract

This paper attempts to develop a linearized model of automatic generation control AGC for an interconnected two-area reheat type thermal power system in deregulated environment. A comparison between genetic algorithm optimized PID controller GA-PID, particle swarm optimized PID controller PSO-PID, and proposed two-stage based PSO optimized fuzzy logic controller TSO-FLC is presented. The proposed fuzzy based controller is optimized at two stages: one is rule base optimization and other is scaling factor and gain factor optimization. This shows the best dynamic response following a step load change with different cases of bilateral contracts in deregulated environment. In addition, performance of proposed TSO-FLC is also examined for changes in system parameters with different type of contractual demands between control areas and compared with GA-PID and PSO-PID. MATLAB-Simulink® is used for all simulations.
