Load frequency control of a multi area power system by optimum designing of frequency based PID controller using seeker optimization algorithm
In this paper, an optimum load frequency control (LFC) of a multi area power system is developed based on a powerful optimization technique called seeker optimization algorithm (SOA) SOA capabilities for solving difficult practical optimization problems has proven and therefore it has gained a massive consideration by researchers. This paper presents a SOA based load frequency controller for elimination of the power system oscillations. A two area power system based on thermal power plants (TPPs) is considered, in which every area is equipped with PID controllers. SOA is used for meeting the optimum parameters of the PID controller, which are acquired by time domain minimization of the objective function. Performance of the proposed controller is compared with genetic algorithm (GA) based PID controller and particle swarm optimization (PSO) based PID controller to indicate the excellence of the proposed algorithm for PID parameters regulation. Simulation results has shown that optimized PID with proposed algorithm has better performance in comparison with previous methods.
