Abstract

In order to speed up the data processing efficiency of the distribution network system,the edge computing technology is applied in the distribution network information physical system.The data computing service is provided at the nearest end of the data source,and the feedback link makes the physical system and the information system closely connected.An optimal allocation strategy of collaborative edge computing resources is proposed,in which the system business requests and computing tasks are distributed to other edge nodes and cloud data centers,and the coordinator performs optimal allocation according to the decision variables of network resource allocation.To identify the vulnerable points in the information system,establish a multi-layer topology model based on the topological characteristics of the distribution network and attack path,calculate the vulnerability of information nodes,and identify the vulnerable points by traversing all attack paths.The experiment results show that the data volume of vulnerable points identified by the distribution network information physical system in this study is the largest,the data volume exceeds 5 000,and the load of edge calculation reaches the highest 1.42 FLOP.
