Abstract: The demand for power is growing rapidly due to fast depletion of fossil Fuels. Under such conditions environment friendly and pollution free Renewable Energy Sources (RES) have emerged. In this paper a new control strategy for 3 phase 4 wire inverter is introduced for effective utilization of renewable energy source with grid. In the proposed control strategy load current ( i.e reduce harmonics), load voltage (i.e reduce harmonics) are compensated using Shunt Active Power Filter(SAPF). The Renewable Energy Source used in this paper is Wind of capacity 1.5MW. The main objective of this paper is nonlinear unbalanced load compensation for power quality improvement. All these works of the inverter is done either individually or combined to overcome the unbalanced effects of nonlinear loads at distribution level. This new hybrid control strategy is simulated in MATLAB/Simulink and compared the results at different times with existing methods.
