A NEW EFFICIENT MPPT FOR WECS IN TROPICAL COUNTRIES

This paper proposes a novel solution to the problems exist in the conventional HCS MPPT algorithm for the WECS. The proposed finding not only solves the tracking speed Vs Control efficiency problems but also makes sure variable wind conditions do not lead HCS in wrong direction. It intelligently adapts variable step size to keep up with rapid change in wind and seizes the perturbation at the maximum at a yield of 100% of control efficiency. The proposed MPPT performs a self - tuning to cope with non - constant efficiencies of Generator - Converter subsystems. In addition, a smart speed - sensor less scheme has been developed to eliminate the use of mechanical sensors. This proposed solution is very efficient the use of mechanical sensors. This proposed solution is very efficient for tropical countries like India under wind changing conditions. The experimental results confirm that the proposed algorithm is remarkably faster and more efficient than conventional HCS.
