This letter proposes a generalized stabilizer-oriented design method for grid-forming virtual synchronous generator (GFVSG) attached to weak-stiffness power networks, where a rate of change of frequency feedforward control strategy (RoCoF-FCS) is put forward to improve frequency stability, enhance damping performance, and avoid aperiodic loss of synchronization (ALoS). In addition, the feedback analytical framework, which connects RoCoF and rate of change of voltage (RoCoV), is proposed to identify both wideband oscillation and ALoS. Finally, the proposed method is validated by time-domain simulations.

集成到弱刚度电力网络中的 GFVSG 的广义稳定器导向设计


本文提出了一种面向弱刚度电力网络的并网虚拟同步发电机（GFVSG）的广义稳定器设计方法，其中提出了频率变化率前馈控制策略（RoCoF-FCS）来提高频率稳定性，增强阻尼性能，避免非周期性失同步（ALoS）。此外，还提出了连接 RoCoF 和电压变化率 (RoCoV) 的反馈分析框架来识别宽带振荡和 ALoS。最后，通过时域仿真对所提出的方法进行了验证。
