Abstract: To enhance resilience of electric power communication network against attacks, an optimal spatial complex network disintegration strategy is proposed. Firstly, a spatial complex network model is developed, incorporating topology and geographic data, and a disintegrating circle is introduced to simulate attacks and damage. Secondly, node traffic and capacity are calculated, aiding in construction of the cascading failure process. Finally, an optimisation model is constructed for the disintegration strategy. And a self-adaptive heuristic algorithm using tabu search is designed to identify the optimal disintegration strategy under the case of cascade failure. Simulations experiments are conducted on two real-world electric power communication networks. Compared with the other three methods, the critical attack strength, the robustness metric and the largest connected component are reduced by an average of 22%, 38% and 36%, respectively. Our strategy can find the optimal disintegration region in the network to disintegrate the network more efficiently.

Keywords: spatial complex network; disintegration strategy; cascading failure; disintegrating circle.
