Abstract: In order to enhance the robustness of interdependent power grids and communication networks, a link addition strategy is proposed, which obeys the partial one-to-one correspondence between power nodes and communication nodes. In this method, the target value of node degree is set and then the number of addition links is determined according to its degree for each node. Our strategy aims to homogenize degree distribution of nodes. Case study on IEEE test systems based on the time-step failure model of nodes shows that the proposed method can obtain better robustness and synchronization of interdependent networks in the case of random and intentional attacks. The proposed strategy can provide guidance on current topic to improve robustness of interdependent networks.
