Compared with 4G communication, 5G communication uses key technologies such as large-scale antennas, ultra-dense networking, and high-frequency communication to greatly improve performance, resulting in increased power consumption of a single 5G base station, multiple sites, and changes in power supply requirements. At present, there are two types of power supply, i.e., nearby power supply and high-voltage DC remote power supply, which can meet the new power supply demand. Aiming at the high-voltage DC re-mote power supply, this paper combs the application of key technologies, comprehensively considers the operation investment cost of peak-shaving and valley-filling economic mode, the busy and idle period of 5G base station service load, and the time-of-use price of peak and valley, and puts forward a feasible working mode. Finally, it looks forward to the development of 5G base station power sup-ply, which provides reference for research or design of its power supply.
