In this paper, a novel fuzzy logic-based control (FLC) strategy is developed to perform multi-function strategy for smooth and controlled operation of three-phase renewable energy system (RES)-based wind energy conversion system (WECS) with grid integration. The inverter acts as an converter to infuse the power obtained from the wind energy and as a active power filter to compensate reactive power demand and load current harmonics. The control strategies in accordance with 3-phase 4-wire unbalanced load tend to appear as a balanced linear load system at grid. The control strategy is developed and validated using MATLAB/Simulink. The proposed controller is compared with PI-based controller and validate that the proposed FLC provide better efficiency by reducing harmonics.
