有意控制的隔离是一种有效的纠正方法，可以最大限度地减少连锁停电导致大面积停电的影响。本研究提出了一种基于约束谱聚类的新方法，该方法在计算上非常高效，并确定了具有最小潮流中断的孤岛解决方案，同时确保每个孤岛仅包含相干发电机。所提出的方法还使操作人员能够约束任何分支，这些分支必须不被断开，以排除在孤岛解决方案之外。利用IEEE 39和IEEE 118总线测试系统的动态模型对该方法进行了测试。针对不同突发事件的时域仿真结果证明了所提出方法的有效性，可以最大限度地减少级联停电导致大面积停电的影响。此外，一个实际规模的系统（英国815辆公交车网络的缩小模型）被用来评估该方法在大规模网络中的效率和准确性。这些模拟表明，作者的方法更有效，大约是10倍，并且比另一种现有的方法更准确，可以实现最小的潮流中断。
Intentional controlled islanding is an effective corrective approach to minimise the impact of cascading outages leading to large-area blackouts. This study proposes a novel methodology, based on constrained spectral clustering', that is computationally very efficient and determines an islanding solution with minimal power flow disruption, while ensuring that each island contains only coherent generators. The proposed methodology also enables operators to constrain any branch, which must not be disconnected, to be excluded from the islanding solution. The methodology is tested using the dynamic models of the IEEE 39- and IEEE 118-bus test systems. Time-domain simulation results for different contingencies are used to demonstrate the effectiveness of the proposed methodology to minimise the impact of cascading outages leading to large-area blackouts. In addition, a realistically sized system (a reduced model of the Great Britain network with 815 buses) is used to evaluate the efficiency and accuracy of the methodology in large-scale networks. These simulations demonstrate that the author's methodology is more efficient, in a factor of approximately 10, and more accurate than another existing approach for minimal power flow disruption.
