A simple and efficient maximized power control of DFIG variable speed wind turbine

The aim of this paper is to present a simple Maximized Power Control for Wind Energy Conversion System (WECS) using Double Fed Induction Generator (DFIG). The control algorithm uses Sliding Mode Control technique (SMC), by the way of the machine inverter. This control strategy, based on stator flux orientation, tracks the maximum power for different wind speeds, and regulates separately the active and reactive powers exchanged between the machine and the grid. The control of our system is tested under fault condition by simulation. Some results are presented and discussed to prove simplicity and efficiency of the DFIG control for WECS.
