Communication Network Selection for Distribution Network Based on Analytic Hierarchy Process

The access of large-scale distributed new energy has high requirements for the protection of new distribution network and communication network, but the selection of the communication network has no definite standard. In this paper, a communication network selection mechanism based on Analytic Hierarchy Process (AHP) is proposed to solve the problem of smart grid communication network selection. This method is based on the principle of decision-making analysis combining qualitative and quantitative analysis of multi- objective complex problems. The weight of indexes at all levels are calculated by the judgment matrix. After the consistency test, the overall judgment matrix is calculated to select the best scheme, which achieves the effect of decomposing and analyzing the communication network of distribution network. Through the analysis of 5 kinds of communication networks, namely optical fiber communication network, 4G network, 5G network, wireless private network and power line carrier, this research constructs the AHP model with accessibility, coverage, economy, reliability and security as the main parameter indexes, and obtains that 5G is the optimal scheme with 26.0178% of the comprehensive weight. Therefore, 5G network is more suitable for the application in the distribution network under the current new energy access.
