IMC and GA Based Fractional Order Controller Design for Load Frequency Control Problem

Abstract

This paper proposes a genetic algorithm based factional order proportional integral derivative controller for load frequency control (LFC) problem. Genetic algorithm used for tuning the proposed controller. Initially the proposed controller is applied to single area power system after that it is applied to two area power system. The turbines known as non reheated and hydro turbine, and all other physical parameters of turbine, governor are validating in practical system. The simulation test in the presence of uncertainties and constraints in the plant parameters, shows improved disturbance rejection, reducing peak overshoots and settling time.
