MPPT Algorithms: Extracting Maximum Power from Wind Turbines

Abstract: This paper proposes a new Maximum Power Point Tracking (MPPT) algorithm employed in Wind Energy Conversion Systems (WECS). One of the major issues concerning HCS is its inefficiency in detecting the peak power when there is a change in wind ·speed. In addition, the HCS produces oscillations in delivered power once this peak is detected. A modified HCS algorithm is proposed in this paper to overcome these limitations. This algorithm employs a variable duty cycle to reduce the oscillations in delivered power once the peak power is detected.
