A novel Elephant Herding Optimization based PID controller design for Load frequency control in power system

This paper presented a new approach known as Elephant Herding Optimization for designing a load frequency controller for single-area non-reheat power system to damping the oscillations of the frequency response in the power system. Elephant Herding Optimization Algorithm is employed to search the parameters of the PID controllers. The PID controller tuned using Elephant Herding Optimization (EHO) techniques. The proposed controller is simulated in MATLAB/SIMULINK for a single area power system with step change in load demand. The proposed method based PID controller improves the performances of the power system in terms of time specifications such as undershoot, overshoot and settling time. The performance is compared with the PID controllers in literature and found to be superior in performance.
