本文提出了一种方法来分裂的电力系统在网络的薄弱环节受到大的干扰，这可能会导致整个系统停电。最终的分裂策略是通过打开具有最小功率交换的传输线路来执行的，即通过最小化区域之间的功率交换。由于一个或多个创建的岛可能会达到一个不稳定的操作点，并因此，导致电力系统停电，所提出的方法包括至少一个黑启动单元内的每个岛，并确保足够的发电能力，以匹配每个岛内的负载消耗。通过确保黑启动可用性和足够的发电能力，并行电力系统恢复计划在任何不测事件的情况下。为了验证的目的，该方法的实施和测试的IEEE 9总线和118总线测试系统。
This paper proposes a methodology to split the power system across the weak areas of the network affected by a large disturbance, which might lead to a total system blackout. The final splitting strategy is carried out by opening the transmission lines with minimum power exchanged, i.e. by minimising the power exchange between areas. Since one or more of the created islands might reach an unstable operating point, and therefore, cause a power system blackout, the proposed methodology includes at least one blackstart unit within each island and assures sufficient generation capability to match the load consumption within each island. By assuring blackstart availability and sufficient generation capability, parallel power system restoration is planned in case of any eventuality. For validation purposes, the methodology is implemented and tested on the IEEE 9-bus and 118-bus test systems.
