With the increase of urban electricity consumption and the popularity of new- type loads

the problem of urban grid blockage demands prompt solution. As a new type of load with high power consumption

wide distribution range and strong regulation potential in urban power grids

5G base stations can effectively alleviate the blockage of urban medium voltage distribution grids by participating in demand response. Therefore

blockage control model of urban medium voltage distribution network considering communication base station demand response is constructed. Firstly

by analyzing the working principle of 5G base station equipment

a power tunable model for 5G base stations is established. Then

a blockage control model for the urban medium voltage distribution network is established

with the objective of minimizing the block-age control cost while taking into account the network trend constraint and the communication constraint of 5G base stations. Finally

the proposed model is verified through an example analysis

which shows that the economic efficiency can be effectively improved while solving the blockage problem of the urban medium voltage distribution network.
