一种高鲁棒性低代价的级联故障模型

A High Robustness and Low Cost Model for Cascading Failures

Bing Wang, Beom Jun Kim

摘要:

本文利用人工构造的无标度网络和真实的电网网络结构对连锁故障问题进行了数值研究。一个顶点的容量被指定为负载(或介数中心性)的单调递增函数。通过使用具有两个自由参数的简单函数形式,揭示了确实有可能使网络更鲁棒,同时花费更少的成本。我们建议,我们的方法,以防止级联保护较少的顶点是特别重要的设计更强大的现实世界中的网络级联故障。

英文摘要:

We study numerically the cascading failure problem by using artificially created scale-free networks and the real network structure of the power grid. The capacity for a vertex is assigned as a monotonically increasing function of the load (or the betweenness centrality). Through the use of a simple functional form with two free parameters, revealed is that it is indeed possible to make networks more robust while spending less cost. We suggest that our method to prevent cascade by protecting less vertices is particularly important for the design of more robust real-world networks to cascading failures.
