For solving load frequency control problem a new method is proposed considering the state feedback controller based on Imperialist Competitive Algorithm (ICA). In this solution, an objective cost function is used to design the gains of the state feedback matrix. The frequency deviation and power flow variations between the two area is decreased by the proposed cost function. For minimizing the proposed cost function the ICA algorithm is considered. The proposed method evaluation is done by applying the design controller 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.
