Abstract

he present research paper discusses differential evolution optimization based modified control configuration for the aim of load frequency control of single-area non-reheated thermal power system. The load frequency control can be achieved by proposed scheme which contains an internal model control (IMC) controller in the internal loop and a FOPID controller in the external loop. Designed of the IMC controller is assembled by low pass filters and a predictive model (PM) which is derivative from the system model using the Routh approximation method. The tuning parameters of low pass filters and exterior loop controller are enhanced by using Differential evolution (DE) optimization. The projected method can sustain faster rejection of external load disturbances and offers better robustness under parameter uncertainty
