The rapidly growing load of 5G base station has brought challenge to the communication operator and urban distribution network.The rational use of spatial and temporal flexibility characteristic of 5G base station load can reduce the power usage cost of base station and alleviate the power supply pressure of distribution network.Focusing on the spatial and temporal flexibility characteristic of 5G base station load,the potential of base station load participating in the demand response through spatial and temporal migration is analyzed.On the basis of backup energy storage scheduling of base station from the perspective of load time migration and the sleep method of base station from the perspective of spatial migration,a collaborative optimal operation model of 5G base station and distribution network is established with the minimum total operating cost of base station and distribution network as the object.The example analysis results show that the participating of 5G base station in the collaborative optimal operation of distribution network based on spatial and temporal flexibility characteristic can effectively reduce the power consumption and operating cost of base station,improve the new energy consumption rate of distribution network,and promote the economic and reliable operation of power grid.
