Output Power Optimization of DFIG-based Wind Turbine

The purpose of this paper is to investigate how to maximize the power output of a DFIG based wind turbine. So, an optimization method based on mathematical analysis has been performed in two generators. So, the exact terms of output power and loss as a function of the slip generator, rotor excitation voltage amplitude and phase angle at different wind speeds are derived. The results show that the maximum output power of turbine does not happen at maximum input power (wind turbine mechanical power). The effect of device parameters on the maximum output power has been investigated and it has been shown these parameters have a greater impact on maximum output power in the machines with lower power. The required modeling is performed using MATLAB.
