Global warming as one of the most critical environmentalproblem facing by the whole world In an attempt to prevent the realization of thesefears, numerous advanced nations around the world havecommitted themselves to controlling emissions of green-house e?ect gases by becomin signatories to the KyotoProtocol. Wind energy is a clean energy that can avoid greenhouse gas (GHG) emissions and emits no air pollution. As wind turbine generators are driven by fluctuating wind, the power quality of the system gets when they are installed into the electric grid. This paper present a control scheme for maintaining power output stability of wind power by using Matlab/ Simulink. A current source inverter (CSI) has been used as a controller for controlling the output voltage and electromagnetic torque of the system. Three resistances are also connected in parallel to the load for the protection of over current in the system. Squirrel-cage type induction generator and Self-excited induction generators are also simulated with the controller.
