AI 中文摘要
传统电网形成（GFM）控制策略常将直流源视为无约束环节，应用于风力涡轮发电机（WTG）时会产生不匹配问题。本文聚焦一次调频，系统研究GFM-WTG的运行特性与基于下垂特性的一次调频之间的不匹配问题，提出一种WTG一次调频与GFM控制的新型协调策略。通过在功率跟踪系数、功率设定值与频率偏差之间建立精心设计的关系，该策略可使GFM-WTG在预设频率限值内持续参与一次调频，同时维持合适的功率点并有效利用允许的功率备用。此外，该方法保留了传统GFM控制的控制结构与动态性能，且固有适应不同风速条件。不同运行场景下的对比案例研究证明了所提策略的有效性与优越性。
英文摘要
Conventional grid-forming (GFM) control strategies often treat the DC source as an unconstrained link, creating mismatches when applied to the wind turbine generators (WTGs). Focusing on primary frequency regulation, this paper systematically investigates the mismatch between the GFM-WTGs behavior and the droop-based primary frequency regulation. To address this issue, a novel coordination strategy between WTG primary frequency regulation and GFM control is proposed. By establishing well-designed relationships among the power-tracking coefficient, power set-point, and frequency deviation, the proposed strategy enables GFM-WTGs to participate consistently in primary frequency regulation within predefined frequency limits while maintaining appropriate power points and effectively utilizing the allowable power reserve. Furthermore, the proposed method preserves the control structure and dynamic performance of conventional GFM control and inherently adapts to varying wind-speed conditions. Comparative case studies under different operating scenarios demonstrate the effectiveness and superiority of the proposed strategy.
