Frequency Regulation of Hybrid Power System by Optimized Adaptive Fuzzy PID Controller

subject

description

In this study, an adaptive fuzzy PID (AFPID) regulator has been proposed for frequency control of hybrid power system. For controller parameter optimization, an upgraded Whale Optimization Algorithm (WOA) has been employed. In the proposed Upgraded WOA (UWOA) technique, a cosine function is incorporated in the original WOA for determining control parameter to manage the position of whales throughout optimization procedure. Furthermore, scaling factors are employed in original WOA to adjust the travel of whales in search procedure. Proposed UWOA technique is employed to design an AFPID controller for frequency regulation of a hybrid power system It is demonstrated that UWOA technique out performs WOA technique in controller design problem and AFPID controller is more effective in controlling the frequency relative to PID controller which is generally taken as a standard controller. Finally, the performance of AFPID controller is equated with PID under different serious uncertain scenarios to illustrate the advantage of AFPID over PID controller.
