具恢复机制的相依电力-信息网络连锁故障传播

为了研究具有恢复机制的电力-信息网络连锁故障传播，基于相依网络理论，建立了IEEE300节点系统电力网与双星型结构信息网的电力-信息相依网络模型.分析复杂网络统计特征参数可知，电力网和信息网均具有小世界和无标度特性.利用相依电力-信息网络的连锁故障模型，对BA，WS和ER 3种不同的相互依存网络进行鲁棒性分析，提出了一种具有恢复机制的相依网络连锁故障传播模型.仿真结果表明，与目标恢复机制和随机恢复机制相比,依赖恢复机制的恢复级别更高，而且这种优势随着故障阈值的减少而提高.

Cascading Failure Propagation of the Interdependent Power-Information Network with Recovery Mechanism

In order to study the cascading failure propagation of the power-information network with recovery mechanism,the IEEE300 node system power network and double-star structural power-information network are established based on the dependency network theory.Calculation of complex network statistic parameters show that both power grid and information network have small-world effect and scale-free network property.Based on the model of the cascading failures of the power-information network,a robustness analysis of three different interdependent networks including BA,WS and ER is conducted,and a model of cascading failure propagation of interdependent network with recovery mechanism is proposed.The simulation results show that the the recovery level of dependency recovery mechanism is higher than the target and the random recovery mechanism.This advantage increases with the decrease of the failure threshold.
