Improved Coordinated LVRT Control Strategy for Grid-forming Direct-drive Wind Turbine

Jia Guo, Yanbo Che, Yijing Chen

Abstract


For grid-forming permanent magnet direct-drive wind turbines during low-voltage ride-through (LVRT), this paper analyses the impact of grid-forming wind turbines on the system, to address the challenge of low wind energy utilization and limited flexibility. A improved coordinated LVRT control strategy involving variable power tracking and rotor overspeed is proposed, which flexibly switches control modes based on the state of the energy storage by combining hybrid energy storage and virtual synchronous generator control. During fault ride-through, the hybrid energy storage module is utilized to store unbalanced energy. When the energy storage capacity is in the warning interval, variable acceleration overspeed is applied to the turbine speed to moderate unbalanced energy and slow down the charging speed, ensuring that the hybrid energy storage power remains in the safety interval. This strategy effectively enhances the LVRT capability and energy utilization of grid-forming units. The correctness of the proposed strategy is verified using the MATLAB/Simulink simulation platform.
