The distributed information energy system is a new stage of energy Internet development and a new form of its application. It is also a distributed and complex information physical system where information and energy are deeply coupled. This paper built a network architecture of a regional distributed information energy system with energy routers as nodes based on the coupled network model of the power communication network and the power network
with the help of complex network theory
correlation coefficient method and correlation matrix method; Combining the different business characteristics of information flow and energy flow
an evaluation index system considering the dual network coupling scale was established
and a multi-index comprehensive evaluation method that can modify subjective empowerment by objective factors was proposed. The simulation verification shows that the calculation of the importance of the nodes can effectively optimize the search process of the backbone network frame of the system
ensure that the nodes and key lines with high importance were covered
and it also verifies the feasibility and rationality of the node importance evaluation mechanism.
