In this paper, we propose the FP PID controller for the load frequency control of 2-area power system. While a PID controller is used in power system, they have many problems as the nonlinearities of power system. So, we are tried to compensate a conventional PID controller by a fuzzy logic-based precompensation approach to robust nonlinearities. Our results show that the proposed control technique is superior to a conventional PID controller in dynamic responses about load disturbances arising in power system. Our design is easily implemented by adding a fuzzy precompenastor to an existing PID controller.
