Renewable Energy Sources are those energy sources which are not destroyed when their energy is harnessed. The model of wind turbine is based on the steady-state power characteristics of the turbine. The stiffness of the drive train is infinite and the friction factor and the inertia of the turbine must be combined with those of the generator coupled to the turbine. In this paper, variable speed wind turbine driving permanent magnet synchronous generator with current controlled voltage source inverter has been proposed. Detailed modeling and control strategies of the overall system has been developed. It is found that under the proposed control strategy the system runs smoothly under randomly and quickly varying wind condition. During both symmetrical and unsymmetrical fault conditions, the system is found stable. Results shows that by using Current Source Inverter (CSI) stability of wind power can be achieved. By using CSI-based Controller voltage source inverter or any separate storage energy system is not required. A model is used to determine the behavior of the wind turbine, induction generator and load.
