Active and reactive power control of DFIG using PI and DPC controllers

This work presents the control of active and reactive power, regardless, of DFIG (Double Field Induction Generator) typically used in electrical energy production and particularly in wind turbines. The machine is connected to a public network and operates as a generator. Its rotor is powered by a voltage of two-level inverter. We offer the control of the DFIG by two strategies, the first is based on the use of conventional PI controller and the second is based on using DPC (Direct Power Control). In the last we will finish by a comparison of performances obtained by the two control strategies.
