针对美国Bonneville电力管理局（BPA）提供的真实的停电数据，研究了连锁故障的空间传播。该分析方法揭示了基于地理距离的空间传播特性。此外，提出了一种关键部件识别方法的基础上的一个新的度量，该度量相结合的信息的预期停电次数和空间距离。在此基础上，提出了一种基于关键部件升级的级联故障缓解策略。在BPA的14年真实的公用事业停电数据上验证了所提出的缓解策略在抑制空间传播方面的有效性。
In this paper, the spatial propagation of cascading failures is studied for real utility outage data from Bonneville Power Administration (BPA). The spatial propagation features based on geographical distances are revealed by the proposed analysis method. Furthermore, a critical component identification method is proposed based on a new metric that combines the information of the expected number of outages and that of the spatial distance. A cascading failure mitigation strategy is further proposed based on the upgrading of the identified critical components. The effectiveness of the proposed mitigation strategy in terms of suppressing spatial propagation is validated on the 14-year real utility outage data from BPA.
