The usage of Wind Energy Conversion Systems (WECS) in the standalone power systems that are increasing in the present scenario with the massive potential because of its high availability and low maintenance.Battery Energy Storage Systems (BESS) is applied to provide the voltage support in the standalone systems. Usually, Proportional Integral (PI) controller are applied for controlling the power in between the power generation and load. However, at thetime of unbalance load conditions, the performance of the PI controller is limited. In addition, with that, PI introduce steady-state errors and has restricted disturbance removalability. The conventional coordinated controllers also suffered from transient conditions at the time of dynamic load variations. To resolve these problems, this paper presents a Fuzzy logic based Proportional Resonant (PR) controller for providing better voltage support in the standalone wind power systems. As an alternative of the conventional PI controller, a PR controller is utilized in the coordinated control system. For optimizing the PR controller gain parameters, Fuzzy Logic Controller (FLC) is utilized. Performance of the proposed Fuzzy-PR controller is compared with the PI controller based coordinated controller. The outcomes demonstrate that the proposed controller delivers better DC voltage support compared with the general PI controller. Furthermore, the Total Harmonic Distortion (THD) of the presented system is very low contrasted with the standard control methods. MATLAB/SIMULINK tool is utilized to validate the system performance
