最近在北美互联网和世界各地观察到多个严重的强迫振荡事件。这些强迫振荡导致功率波动，限制功率传输能力，损坏设备，并无限期地持续下去，直到驱动源被定位和移除。本文提出了一种综合的方法来减轻强迫振荡。一旦检测到受迫振荡，就可以使用新的源定位算法来基于振荡模式角来定位源，而不需要系统拓扑信息。如果不能快速定位和移除源，则可以激活控制策略以调制基于公用事业规模逆变器的电池储能系统（BESS）的有功功率，以将强迫振荡的能量降低到安全水平，并允许足够的时间来定位确切的源。使用在2019年1月11日北美强迫振荡事件和其他实际电网事件期间收集的测量结果验证了所提出的源定位算法，而在复制的2019年1月11日强迫振荡事件下使用Eastern Interconnection动态模型验证了所提出的控制策略。仿真结果表明，所提出的源定位算法能够准确识别强迫振荡源，所提出的控制策略能够显著降低强迫振荡能量。
Multiple severe forced oscillation events have recently been observed across the North American interconnections and around the world. These forced oscillations have caused power swings, limited power transfer capability, damaged equipment, and persisted indefinitely until the driving source was located and removed. This paper proposes a comprehensive method to mitigate forced oscillations. Once a forced oscillation is detected, a new source location algorithm can be used to locate the source based on the oscillation mode angle without requiring system topology information. If the source cannot be quickly located and removed, a control strategy can be activated to modulate the active power of utility-scale inverter-based battery energy storage systems (BESSs) to reduce the energy of forced oscillations to a safe level and allow sufficient time for locating the exact source. The proposed source location algorithm is validated using measurements collected during the January 11, 2019 forced oscillation event in North America and other actual grid events, while the proposed control strategy is verified using the Eastern Interconnection dynamic model under the replicated January 11, 2019 forced oscillation event. The simulation results demonstrated that the proposed source location algorithm can accurately identify the forced oscillation source, and the proposed control strategy can significantly reduce forced oscillation energy.
