Participation of a DFIG Based Wind Energy Conversion System in Frequency Control

In this article, we study the participation of a DFIG-based wind turbine in frequency control in the event of a fault affecting the grid frequency. The method presented in this paper is based on the combination of primary control and the inertial response: The first controller is to produce less power than its maximum available. Therefore, we will create an active power reserve to exploit to support production in the grid frequency drop event. The second makes it possible to exploit part of the kinetic energy stored in the turbine at the start of the occurrence of the frequency fault to support the production.Therefore, this work presents the integration of these control structures as well as the study of their performance in the case of a wind turbine based on DFIG and controlled by the Backstepping technique. The results are obtained by a simulation in the MATLAB / SIMULINK environment.
