随着可再生能源和其他基于逆变器的资源（IBR）的渗透率不断提高，强迫振荡事件已成为一个具有挑战性的问题，特别是当强迫振荡频率与主导自然振荡频率一致时。一个严重的强迫振荡事件会恶化电力系统的动态稳定性，损坏设备，并限制功率传输能力。本文提出了一种二维扫描强迫振荡电网脆弱性分析方法，以确定在系统中的区域/区域，是关键的强迫振荡。这些关键区域/区域可以进一步被认为是用于部署强迫振荡阻尼控制器的有效致动器位置。此外，还提出了通过IBR的有功功率调制控制，以减少强迫振荡对整个电网的影响。所提出的方法证明了通过一个合成得克萨斯州电力系统模型的案例研究。仿真结果表明，受迫振荡的临界区域与固有振荡的参与程度较高的区域有关，所提出的基于IBRs的振荡阻尼控制器能有效地减小受迫振荡对整个系统的影响.
Forced oscillation events have become a challenging problem with the increasing penetration of renewable and other inverter-based resources (IBRs), especially when the forced oscillation frequency coincides with the dominant natural oscillation frequency. A severe forced oscillation event can deteriorate power system dynamic stability, damage equipment, and limit power transfer capability. This paper proposes a two-dimension scanning forced oscillation grid vulnerability analysis method to identify areas/zones in the system that are critical to forced oscillation. These critical areas/zones can be further considered as effective actuator locations for the deployment of forced oscillation damping controllers. Additionally, active power modulation control through IBRs is also proposed to reduce the forced oscillation impact on the entire grid. The proposed methods are demonstrated through a case study on a synthetic Texas power system model. The simulation results demonstrate that the critical areas/zones of forced oscillation are related to the areas that highly participate in the natural oscillations and the proposed oscillation damping controller through IBRs can effectively reduce the forced oscillation impact in the entire system.
