Abstract—With the rapid development of electrical power systems nowadays, stability and reliability features of the network have to be considered strongly to keep the system under normal working conditions. Because of the complexity of a large-scale or multi-area power system, load disturbances can appear randomly at any point of the network which will cause the deviations of the frequency and tie line power. As a result, the frequency and power generation in the system will be affected. In order to keep the frequency at the nominal value, this work investigates efficient approaches by using advance controllers: PID and fuzzy logic controller. Simulation results will be implemented by using Matlab/Simulink program for a three-area interconnected power system to verify efficiencies of the proposed control schemes.
