A Sensor-Less Based MPPT Scheme for DFIG Wind Conversion System

Abstract

Recently, the focus of wind power systems has tended to be on obtaining high maximum power point tracking (MPPT) efficacy without mechanical sensors, fast-tracking wind speeds (WSs), and high performance under unpredictable WSs along with an efficient control system. Variable-speed wind power generation now commonly uses double-fed induction generators (DFIG) with partial-size back-to-back converters. How to get power at maximum value with different wind speeds is the biggest issue with the wind energy system. Tracking involves a variety of techniques and an understanding of mechanic sensors and system characteristics in order to attain the maximum output power. Prices will rise as a result of these techniques in order to improve the maximum power point tracking. This research suggests utilizing an MPPT control strategy that is based on a sensorless scheme to harvest the highest power possible from wind turbines with DFIGs. In MATLAB/ SIMULINK, comprehensive models of various DFIG system configurations are completed.
