摘要：

Wind energy conversion systems (WECSs) based on doubly fed induction generators (DFIGs) are considered prominent technologies in wind energy systems. However, complying with grid code requirements necessitates maintaining wind turbine connectivity during network voltage dips. As the stator of the DFIG is directly linked to the grid, the generator stability is mostly affected by grid voltage dips. This paper proposes a direct power control strategy based on a reference generation approach to enhance the transient behaviour of DFIG during grid voltage dips and the subsequent recovery period. By eliminating the reliance on sequential decomposition methods and reducing the need for crowbar protection, the proposed control method achieves improved performance. The control method employs a sliding mode control strategy to expedite convergence time, while the control parameters are tuned using a fuzzy logic strategy to facilitate adaptation to external disturbances. Results demonstrate that the proposed strategy reduces rotor overcurrent, ensures a stable reactive power supply during voltage dips, and preserves the grid connection of the wind turbine.
