Abstract: In this research paper, an attempt has been made to design a Fractional order PID (FOPID) controller employed for centralized and decentralized frequency control in a restructured power system. The controller gains are optimized by Moth Flame Optimization algorithm (MFO), with Integral Time Absolute Error (ITAE) as objective function. The performance of the FOPID controller is compared with that of conventional PID controller under various contract scenarios. It is observed that FOPID as a frequency error damping controller, the steady state and dynamic performance of the proposed power system is enhanced.
