Dynamic Participation of a DFIG-based Wind Turbine Controlled using Backstepping in Frequency Regulation

as the wind power generation continue to flourish worldwide, the power system will inevitably confront multiple challenges with regards to their high-level of penetration. Therefore, wind energy conversion systems (WECSs) must quickly take interest in ancillary services. For instance, the need for participating in frequency regulation become greater with an important penetration rate of wind turbines. A significant wind production will lead to the shutdown of many traditional power generators, which will reduce the primary frequency regulation reserves needed to be maintained in order to ensure the reliability and the stability of the electrical grid. Accordingly, the aim of this paper is to propose an effective and simple equivalent model for a DIFG-based wind energy conversion system participating in the primary frequency control. The additional control strategy is used to lower the generated power so as to maintain at any moment a certain reserve of active power that can be used later when a frequency fault occurs. Simulation results using Matlab/Simulink software demonstrate the effectiveness of the proposed control strategy.
