电网脆弱性:一种复杂网络方法

Power grids vulnerability: a complex network approach

S. Arianos, E. Bompard, A. Carbone, F. Xue

摘要:

电网对停电的反应模式与复杂网络相似。停电序列遵循幂律,因为复杂系统在临界点附近运行。本文在复杂网络理论框架下分析了电功率电网对意外停电和恶意停电的容忍度。特别地,通过引入节点之间的距离的新概念来修改称为效率的量。在此基础上,提出了一种新的评价电网性能的参数--净容量。效率和净能力之间的比较提供了估计样本网络的脆弱性,在这两个指标。

英文摘要:

Power grids exhibit patterns of reaction to outages similar to complex networks. Blackout sequences follow power laws, as complex systems operating near a critical point. Here, the tolerance of electric power grids to both accidental and malicious outages is analyzed in the framework of complex network theory. In particular, the quantity known as efficiency is modified by introducing a new concept of distance between nodes. As a result, a new parameter called net-ability is proposed to evaluate the performance of power grids. A comparison between efficiency and net-ability is provided by estimating the vulnerability of sample networks, in terms of both the metrics.
