Electric power information physical fusion system effect relationship sorting method considering running topology characteristics

Abstract

The invention discloses an electric power information physical fusion system effect relationship sorting method considering running topology characteristics. The method comprises the following steps that 1, a complex network model is built for an electrical network information physical fusion system; 2, an information layer node importance comprehensive evaluation matrix is defined, wherein importance reference indexes are the number of degrees of nodes, betweenness, the shortest distance with control center nodes and clustering indexes; 3, a physical node load is gotten; 4, on the basis of the interactive relationship, the information layer node importance comprehensive evaluation matrix serves as a weight, and a physical layer node weighted node load corresponding to the weight is calculated; 5, according to the physical layer node weighted node load result obtained in the step 4, physical layer nodes are sorted, and the sorted result is equivalent to importance sorting of the interactive relationship corresponding to the physical nodes. Accordingly, help is provided for a follow-up study and actual electric power information physical fusion system running control management.

Description

technical field [0001] The invention belongs to the technical field of electric power system automation, and in particular relates to a method for sorting interaction relations of an electric power information physical fusion system considering characteristics of an information layer and a physical layer. Background technique [0002] With the development of the power industry, my country's power system has developed into one of the largest, largest and most complex man-made networks, which puts forward higher requirements for power system control and protection. Under the background of the smart grid in the new environment, the traditional power system has developed into a power information-physical fusion system. The physical layer is the primary power equipment, and the information layer is the intelligent information equipment and its communication network that provide 3C support for the physical layer. [0003] The information layer interacts with the physical layer, th...

Problems solved by technology

The traditional identification and ranking methods of important nodes start from a single information layer or physical layer without considering their interaction, which makes the ranking results not comprehensive and accurate enough in the environment of power cyber-physical fusion system
