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.
