摘要

研究复杂网络的级联故障对评估网络系统的稳定性具有重大意义.在经典的线性负载容量模型基础上，通过探测网络的社群结构，有选择地对社群边界节点的容量附加二次容忍值，建立级联故障抵制模型.在级联故障仿真中，采用不同干扰策略对IEEE118标准电网、国内现实电网等模拟故障过程.仿真结果表明，所建抵制模型通过对社群边界节点的容量进行二次扩容，能以较小的成本提高网络的稳定性，同时发现社群边界节点具备“防火墙”和“引爆点”的双重功能.通过将单一网络推广到两层耦合网络，发现在成本可控下新模型对相依网络的级联故障依然具备较好的抵制能力，说明本文所提模型具备一定的适应性.

Abstract

Cascading failures in complex networks is of great significance for the stability assessment of complex networks. Based on the classical linear load and capacity model

a model resisting cascading failures is built by detecting the community structure of the networks and adding secondary tolerance value to community boundary nodes. In the process of cascading failures

different strategies are used to attack IEEE standard grids

domestic real grids. The simulation results show that the model can raise networks stability with lower cost by adding secondary tolerance value to community boundary nodes

finding that the community boundary nodes have the dual functions of "firewall" and "tipping point". By simulating the two-tier coupled networks except for single networks

the new model is also found abler to resist cascading failures in interdependent networks

which indicates that the proposed model has some flexibility.
