Sliding Mode Control of Doubly-fed Induction Generator in Wind Energy Conversion System

The majority of wind turbines operate in variable speed for improving the system efficiency compared with fixed speed generator. This thanks to the adjustment of the generator speed with that of the optimal wind which allows to extract the maximum output power developed by the turbine. The increasing share of wind energy in the existing electricity system has created new opportunities and new challenges. Dual feed machines are the most relevant because of their several gain compared to fixed speed wind turbines. dual feed generators can improve the stability and energy quality of existing electrical systems. In this paper we focus on generating electricity by modeling the Doubly Fed Induction Generator and the development of his order to manage powers and provide system services. In the end, the simulation of grid side and wind turbine side is realized and the obtained results are discussed. The system is modeled and simulated by using Matlab/Simulink package under different wind speed.
