Abstract: Energy from wind is turning out to be a very promising alternative source technology in present and future power sector as it is environment-friendly and long-lasting with technological enhancements. Moreover, it occupies less space and has relative cost competitiveness. In the utility grid, the penetration of wind energy systems is expanding as the research progresses to capture greatest available wind power and operate the wind turbine (WT) with maximum possible aerodynamic efficiency. For this to accomplish a tracking controller is required to extract greatest wind power at all instants in the wide range of wind speeds. This paper presents a simple control technique for optimal power extraction from cut-in to rated wind speed range by sensing the dc-link power. It also embraces mathematical modeling of wind energy conversion system. The proposed algorithm shows excellent tracking capability under fluctuating wind conditions as revealed by power speed characteristic obtained in a wind energy system. The effectiveness of proposed strategy is verified by Matlab simulation.
