This paper represents the modeling and simulation of wind energy based grid connected distributed generation system. A control scheme is presented to control the power flow of the inverter. The controller is able to restore the pre fault condition very quickly. The grid side controller is able to manage the constant dc-link voltage while maintaining the power injection according to the wind speed variations. The performance of the system for wide range of wind speed is presented. The battery is considered for energy storage and is directly connected to the dc-link. The results for variation in load and fault conditions are shown.
