Competition over resources optimized fuzzy TIDF controller for frequency stabilization of hybrid micro‐grid system.

Summary: This paper presents a comprehensive analytical study of conventional proportional‐integral‐derivative (PID) controller and fuzzy logic controller in a hybrid micro‐grid system (HMGS) for frequency stabilization. Conventional PID and fuzzy logic controllers are tuned by the competition over resources (COR) algorithm. The performance of proposed COR based fuzzy tilt‐integral‐derivative with filter (FTIDF) method is demonstrated on an interconnected HMGS. HMGS completes with variety of energy storage systems and different renewable generation sources. The system analysis is performed under number of scenarios. The scenarios include load fluctuations, variations in wind speed, and sun irradiance. The supremacy of FTIDF controller is established by comparing the results with CRO tuned conventional PID with filter (PIDF), fuzzy PIDF and fuzzy TIDF controllers. The effectiveness of the proposed system is investigated using simulation studies, which are performed using MATLAB/SIMULINK software. [ABSTRACT FROM AUTHOR]
