Embodiment Construction

[0030] The present invention will be further described below.

[0031] The method for sorting the interaction relationship of the power cyber-physical fusion system considering the characteristics of the information layer and the physical layer includes the following steps:

[0032] Step S1, establishing a complex network model for the cyber-physical fusion system of the power grid. For the physical layer: the substation is a point, and the transmission line is an edge; for the information layer: the 3C node corresponding to the physical layer is a point, and the communication line is an edge.

[0033] Step S2. Define the comprehensive evaluation matrix of the importance of information layer nodes. The reference index of importance is the degree, betweenness, shortest distance to the control center node and clustering index of the node.

[0034] Step S3, calculating the physical layer node load.

[0035] Step S4. According to the interaction relationship, the value of the in...

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...
