Power grid multi-attribute important node evaluation and planning method

The invention belongs to the technical field of power system automation, and particularly relates to a power grid multi-attribute important node evaluation and planning method. The method comprises the following steps: establishing a complex network topological graph of a dependent network by performing data acquisition on a target information physical fusion system; establishing a fault propagation model for the dependent network, and calculating the influence of attacked information nodes on a physical system and an information system; respectively establishing survival condition numbers of the information nodes and the physical nodes, and respectively evaluating the vulnerability of the information nodes according to the difficulty degree of failure of the information nodes; evaluating the hub degree of the information node by taking the betweenness centrality and the degree centrality of the node as hub degree indexes according to the topological structure of the complex network; and according to the infl
