Résumé : 

In this paper, we present the modeling and control of the wind energy conversion systemsbased on the doubly fed induction generator fed by AC/AC matrix converter. Firstly, wedeveloped the models of the different elements of the conversion chain. After, we consider thevector control strategy of the active and reactive powers in order to ensure an optimum operation.Finally, the dynamic model of a doubly fed induction generator and wind turbine grid connectedsystem is determined in the d-q synchronous reference frame.Therefore, the powers control isverified using software Matlab/Simulink. The behaviours of the sub-synchronous and supersynchronous operation modes is presented and discussed. The results prove that the power controlstrategy is well adapted to this kind of system.
