Research on the robustness of power information dependent networks based on complex networks

The power information dependency network improves the intelligence of the grid but also increases the complexity of the network, so the study of the robustness of the dependency network is one of the challenges that must be solved for the smart grid. In order to achieve this goal, firstly, the single-layer grid and two-layer dependent network models are established based on complex networks; secondly, evaluation metrics are proposed to compare and analyze the robustness of single-layer grid and dependent network with different failure modes, and the simulation results are verified with IEEE30 and IEEE118 node systems, which show that the robustness of dependent network is lower than the robustness of single-layer grid; finally, a failure mode is proposed to meet the actual grid. Finally, a failure mode study is proposed to simulate the robustness of the actual grid dependent network, and the results also show that the robustness of the actual dependent network is lower than the robustness of the single-layer grid.
