State Feedback Controller Based Imperialist Competitive Algorithm for Load Frequency Control Problem
چکیده
ABSTRACT: Decentralized load frequency controller (LFC) for multiarea power system using the state feedback controller based on Imperialist Competitive Algorithm (ICA) is developed and studied in this paper.In this method, an objective cost function is used to design the gains of the state feedback matrix. The proposed cost function decrease the frequency deviation and power flow variations between the areas. In this paper, the ICA algorithm is used to minimize the proposed cost function. For the purpose of the proposed method’s evaluation, the design controller is applied to a two area power system with considerations regarding governor saturation and the results are compared to the one obtained by a classic PI controller. Simulation results show better operation and improved system parameters such as settling time and step response rise time using the proposed approach. keywords: Frequency Control, Imperialist Competitive Algorithm, State feedback controller, Frequency deviation
