Abstract:

<p>A simple sensor-less maximum power point extraction scheme for a Permanent Magnet Synchronous Generator (PMSG) connected wind turbine supplying power to a DC micro-grid has been proposed in this paper. The wind extraction topology has a small-scale wind turbine directly coupled with a PMSG. The three phase output voltage of the generator has been rectified using a 3φ uncontrolled rectifier and a DC–DC buck converter whose output voltage is controlled as per the modified Maximum Power Point Tracking (MPPT) algorithm. The algorithm changes the resistance value as viewed from the source and in turn affects the rotor speed to change such that Power Coefficient (Cp) of the wind turbine reaches its maximum value. This algorithm detects quick wind speed and reaches its maximum power point (MPP) by adjusting the slope of the power with respect to duty ratio of converter. The proposed system has been developed and simulated using MATLAB/SIMULINK under varying wind conditions and the maximum power is obtained. © 2018 Academic Press. All Rights Reserved.</p>
