Abstract: A growing number of nations have recognized the economic, social and environmental benefits of renewable energy and are enacting tax incentives and other policy measures favorable to renewable technologies. To analyze the various aspects of grid interconnection with DFIG using MATLAB. This paper is based on the performance of renewable source of energy (wind). This analysis is based on the MATLAB Simulation, With the help of this software & using simulation technique analysis of Performance is done & Power Quality Problems such as voltage sag, voltage flicker and unbalance voltage due to fault are also analyzed. This paper shows the power electronic grid interconnection supports the variable speed wind power, real and reactive power control, and reduces the influences of fluctuations in the wind such as voltage flickers. Nonetheless, it generates other problems due to the switching devices of the power converters. One problem of the grid interconnection is harmonic distortions of the grid currents and voltages. The harmonic distortions degrade the power quality. This leads to more severe problems in the power system such as transformer saturations, failure of protective devices, etc.
