In this paper a Fuzzy Logic based load frequency control system (LFC) with Superconductor Magnetic Energy Storage System (SMES) in a multi area electric power system was explained. If a large power imbalance is suddenly happened in a multi area power electric system, generation units and also consumer sides will be affected by the distortion in the energy balance between both two sides. This imbalance is initially handled by the kinetic energy of the system rotating components such as turbines, generators and motors, but, eventually, the frequency will change. Therefore, Load Frequency Control (LFC) is considered as one of the most challenging issues in power system control and operation. PID type controllers are conventional solutions for LFC. The parameters of the PID controllers have been tuned traditionally. In this paper, a PID controller is applied for the LFC problem to stabilize the system after disturbances like load changing and further oscillations are damped by using SMES. To illustrate the application of the method, a multi area network with some uncertainties is provided. Finally the results of the Load Frequency controller are compared without SMES and SMES and also effect of variation of parameters for PI like (Ki) are studied. It is also further studied the performance of the system with PI and FLC techniques. The simulation results show the success and the validity of the PID controller in compare with the FLC controller.
