Design of Load frequency controller using Whale Optimization Algorithm (WOA)

This research work focuses on drafting a Load frequency controller that is interconnected with a Single area thermal power system for a Hybrid Distributed generation system. Whale Optimization Algorithm(WOA), a meta-heuristic, nature inspired optimization method is applied to obtain PID (Proportional-Integral-Derivative) controller’s gain value. The efficiency of the dynamic system is observed. The observations are discussed and compared with the efficiencies of other approaches like Harmony search (HS), Flower pollination algorithm (FPA) and Particle swarm optimization (PSO). The proposed system exhibits its robustness in the frequency deviations’ profile with settling time. MATLAB R2010a was used to simulate the same.
