Abstract: To address the challenges of coordinating multiple frequency regulation resources in permanent magnet synchronous (PMS) wind farms and mitigating excessve reactive power fluctuations during frequency regulation,a model predictive control (MPC)-based coordinated predictive control strategy is proposed. First,based on the structural block diagram of the underlying controller in PMS wind farms,a dynamic model of multiple frequency regulation resources is established,elucidating their mechanism for participating in main grid frequency regulation. Then, combined with the power system swing equation,a grid frequency response model is constructed to accurately predict the system's frequency dynamics during active power disturbances. Finally,with the optimization objective of suppressing main grid frequency deviations,the coordinated control of multiple frequency regulation resources is achieved while comprehensively considering the physical safety constraints of each type of regulation resource. Validation using a two-area system demonstrates that,compared to traditional droop control methods,the proposed coordinated predictive control strategy increases the lowest frequency point of the main grid by 0.06Hz and reduces the wind farm’s reactive power by 2.4 Mvar, confirming its superiority in enhancing main grid frequency stability. This study provides theoretical insights for the comprehensive utilization of multiple frequency regulation resources in renewable energy power stations.
