The world has turned its focus towards renewable energy sources due to the depletion of fossil fuels. Nuclear energy seems to hold the long term solution to this energy problem. However we know that nuclear energy has its own downfall in the production and the disposal of the radioactive waste produced. Wind energy and solar energy have gained considerable importance. The main problem associated with wind energy is that, due to unpredictable and varying wind speed, the system cannot be used to supply a constant load demand. This also leads to problems in attaching the wind generation system to a common bus. The same problem exists with solar power generation as well. To overcome this problem in this paper we have proposed a solution by adding a fuel cell, ultra capacitor stack as an auxiliary energy source. This energy source is used to supply the power demand during lack of wind. Furthermore the system is designed in such a way that these fluctuations are tolerated and the system is relatively free of harmonics in by using a new topology
