A Comparative study between direct and indirect power control of DFIG within wind power system by the stator flux orientation technique

Within the context of the current climate change, the new energies, namely the wind energy, constitute a good alternative to conventional energies. In this article, we propose a modeling of the Doubly Fed Induction Generator (DFIG), in order to control, with two methods, (direct and indirect) the active and reactive power generated by the stator in an independent way. In order to do this, a model was established for each element of the wind turbine, and then the technique of vector control was used (flow orientation) by two methods to control this machine. Finally, simulation has been used to assess and compare the system’s performance in terms of setpoint tracking and resilience to parametric DFIG fluctuations.
