Comparative performance analysis of hybrid differential evolution and pattern search technique for frequency control of the electric power system

Abstract In the current situation, operation and control of power system is a greater challenge. The most significant situation in load frequency control. present work, hybrid differential evolution pattern search (hDE-PS) method has been suggested for regulation electrical systems. Fractional-order proportional integral derivative (FOPID) controller implemented design analysis purpose. applied two systems model, i.e., 2-area diverse source with/without HVDC linkage thermal system. performances have evaluated with PID optimal controller. simulation results indicate that are enhanced approach identical structure. Robustness analyzed by variation random parameters. (hDE-PS tuned FOPID) further investigated performance recommended equating other newly available approaches, like Genetic Algorithm (GA), Bacteria Foraging Optimization (BFOA), Particle Swarm (PSO), BFOA PSO (hBFOA-PSO), multi-objective Non-dominated Sorting (NSGA)-II Firefly similar
