Research on the Robustness of the Information System Influenced by the Power System Based on the Cyber-physical Coupling System

  • 摘要: 为研究耦合网络单侧网络拓扑结构对另一侧网络鲁棒性的影响,首先基于复杂网络理论对电力信息耦合网络进行建模,其次建立级联失效传播模型,分析电力信息耦合网络电力侧网络拓扑结构特性对信息侧鲁棒性的影响,最后针对单侧电力网的拓扑结构特点,分别提出基于介数删边策略、保护高介数节点策略和基于最短路径加边策略。仿真结果表明,无论在随机节点攻击模式下还是高度数节点攻击下,BA-118耦合网络单侧信息网都表现出强于WS-118和ER-118的单侧信息网的鲁棒性,并且基于介数删边策略、保护高介数节点策略和基于最短路径加边策略在对应耦合网络单侧信息网中都能提高其鲁棒性。

     

    Abstract: To study the influence of the topology of one side of the coupling network on the robustness of the other side, firstly, the power information coupling network is modeled based on the complex network theory, and then the cascaded failure propagation model is established to analyze the influence of the topology characteristics of the power side of the power information coupling network on the robustness of the information side. Finally, according to the characteristics of topology of one-sided power network, the strategies based on the betweenness edge deletion, the high betweenness node protection and the shortest path edge addition are proposed respectively. The simulation results show that the single side of information network of BA-118 coupling network is stronger than that of WS-118 and ER-118, no matter in random node attack mode or high-degree node attack mode, and the strategies based on the betweenness edge deletion, the high betweenness node protection and the shortest path edge addition can improve the robustness of the information-sided network of the coupling networks correspondingly.
