This paper lays emphasis on need of renewable energy sources for power due to increase in the demand for energy and depletion of conventional sources of energy. We propose to integrate the renewable energy with our DC Micro grid. In this paper we study the interfacing of the Solar P-V , Wind Turbine with the DC Micro grid through the rectifier, Buck Boost and Fly back converter respectively. We present a model of a wind turbine using a Fly back converter as it can provide isolation due to the use of high frequency transformer in its design. This isolation provides the advantage of protection of the DC link from any fault on the wind turbine or synchronous generator side. The emphasis is to investigate performance of P-V with Buck Boost converter. We also apply the Perturb and Observe MPPT tracking technique on the respective converters at varying operating points to extract the maximum power and keep the DC-link voltage constant. Further the model of wind generator and solar energy performance on the MATLAB/SIMULINK environment is investigated..
