oa Power control of wind generator using PI regulator

Recently, the wind power represents an important potential. In order to exploit this potential efficiently, the wind turbine must operate at different speeds when the wind speed changes. To deal with the changes in wind speed, this study presents essentially the modeling and power control of Wind Energy Conversion Systems (WECS) based on Doubly Fed Induction Generator (DFIG) by using the vector control which relies on PI regulator [1]. Firstly, the model of the wind energy conversion systems is shown. Then, the control system is applied to ensure that our objective is achieved. This control consists of two parts: the first is to maximize the energy extracted from the turbine using the Maximum Power Point Tracking strategy (MPPT), and the second part is to control the DFIG’s power using the PI regulator. Finally, the results will be presented in Matlab/Simulink environment.
