随着城市用电量的增加和新型负荷的广泛加入,城市电网阻塞问题亟待解决。5G基站耗电量大、分布范围广、调节潜力强,其参与需求响应可以有效缓解城市中压配电网阻塞。因此,构建了考虑通信基站需求响应的城市中压配电网阻塞管控模型。首先,通过分析5G基站工作原理,建立5G基站功率可调模型;然后,考虑网络潮流约束和城市通信需求约束,以阻塞管控成本最小为目标,建立城市中压配电网阻塞管控模型;最后,算例验证所提模型不仅可以解决城市中压配电网阻塞问题,还可有效提高经济效益。

With the increase of urban electricity consump⁃tion 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 regula⁃tion 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.
