DC Connection of Wind Power Generation System with Capacitor Energy Storage

This paper presents the performance of connecting two wind generation systems with the energy storage at the DC side. Energy storage is desirable to be installed to keep constant output from the wind power generation system. The DC connection of two wind power generation system helps to exchange power between the two systems and can suppress the disturbance of the output power to the utility systems more longer than the stand alone system. This effect is easily achieved without any additional control. The controller measures only the common DC side capacitor voltage of the local system. MATLAB/simulink simulation verifies the better performance in a certain situation
