论文摘要
网络冗余是对稳健性至关重要的空间网络结构属性之一，以防止功率网络中的级联故障。级联故障中网络分区的等待时间分布解释了空间网络结构如何影响级联行为。研究了与第一个也是最大的网络分区相关的两个等待时间事件，以在不同的网络冗余下进行级联故障。借助合成功率网络，可以系统地分析网络分区的等待时间分布，以获取各种网络冗余。当网络冗余增加时，等待时间分布会相应地向右移动。同时，最大分区的尺寸减少，而它们的数量统计增加。法国，德克萨斯州和波兰的现实电力网络也显示出等待时间分布的趋势。
Network redundancy is one of the spatial network structural properties critical to robustness against cascading failures in power networks. The waiting-time distributions for network partitions in cascading failures explain how the spatial network structures affect the cascading behaviors. Two waiting time events associated with the first and largest network partitions are studied for cascading failures under different network redundancies. With the synthetic power networks, the waiting-time distributions of network partitions can be systematically analyzed for various network redundancies. Waiting-time distributions shift to the right accordingly when network redundancies increase. Meanwhile, the sizes of the largest partitions decrease while the numbers of them increase statistically. The realistic power networks of France, Texas, and Poland also show the same trend for waiting-time distributions.
