The Load Frequency Control (LFC) problem is one of the most important subjects in the electric power system operation and control. In practical systems, the conventional PI type controllers are applied for LFC. In order to overcome the drawbacks of the conventional PI controllers, PI and PID Fuzzy controllers are considered for LFC problem. The parameters of the proposed Fuzzy controllers are tuned using Genetic Algorithms (GA). A multi area electric power system with a wide range of parametric uncertainties is given to illustrate proposed method. The simulation results visibly show the validity of proposed controllers in LFC problem.
