The invention provides a centrality analysis-based power distribution and utilization communication network source distribution reconfigurable method. A power distribution and utilization communication network includes a physical network and a virtual network. The method includes the following steps that: the physical network and the virtual network are described as weighted undirected graphs; a service provider applies for resources from the physical network in the form of initiating a virtual network request, and the important degree of a communication node in the power distribution and utilization communication network is defined; and with physical network topology and virtual network topology adopted as input, the virtual network is made to use a virtual node with high centrality preferentially. According to the method of the invention, the position importance of the communication node in the power distribution and utilization communication network is considered in a network virtualization process, so that resource reconfigurable distribution efficiency can be improved, overall reliability can be improved. The method can provide a high-reliability and high-quality communication means for industrial control signals and is particularly suitable for communication requirements of application such as power distribution networks, microgrids and new energy.
