The power consumption of a single 5G station is 2.5 to 3.5 times higher than that of a single 4G station. The main factor behind this increase in 5G power consumption is the high power usage of the active antenna unit (AAU). Under a full workload, a single station uses nearly 3700W.
Although the absolute value of the power consumption of 5G base stations is increasing, their energy efficiency ratio is much lower than that of 4G stations. In other words, with the same power consumption, the network capacity of 5G will be as dozens of times larger than 4G, so the power consumption per bit is sharply reduced.
A substantial quantity of power is used by 5G BS. Radio transmitters and processors are a couple of base station components whose power consumption can be optimized with the use of PSO. PSO can assist in lowering the consumption of energy while preserving network performance by modifying parameters like transmission power and duty cycles.
It also provides a way to solve the problem of 5G energy consumption. This paper puts forward a scheme to install photovoltaic energy storage system for 5G base station to reduce the power supply cost of the base station, compares it with the energy consumption cost of 5G base station in different situations, and analyzes the economy of the scheme.
The base station’s average energy consumption during a certain time period has been estimated. A range of optimization approaches, namely PSO, ABC, and GA, have been employed to obtain the best possible (optimal) cost for the system.
At present, the typical power and peak power of a base station are about 6 kW and 9 kW, respectively, and they will increase to 14 kW and 19 kW with the application of the millimetre wave and 5G new technologies in the existing frequency band (Huawei, 2020).
