In this paper, an efficient and effectual optimization algorithm called Gravitational Search Algorithm (GSA) is suggested to optimally tune the PID-FUZZY parameters toward accurate frequency control of two-area power system. An effective and precise optimization algorithm i.e., GSA has been constructed based on the gravity law and mass interactions. In this algorithm, the explorer operators are a masses collection which interacts with each other according to the motion laws and Newtonian

To appropriately and accurately confirm the dynamic performance of suggested GSA-based PID-Fuzzy, four performance indexes, i.e.: ISE, ITSE, IAE and ITAE have been considered as objective functions. Furthermore, the simulations results by the suggested GSAbase PID-FUZZY have been compared with the simulation results based on Particle Swarm Optimization (PSO) and Artificial Bee Colony (ABC) algorithms which are generally realized as conventional heuristic algorithms and extensively applied by the researchers and scholars. Finally, optimal GSA-based PID-FUZZY presents a high dynamic performance as compared to PSO-based PID-FUZZY and ABC-based PID-FUZZY.
