Firstly, in terms of energy equipment, the electrical component characteristics of the 5 G base station's constituent units are modeled, including air conditioning loads, power supply systems, and energy storage systems.
This section integrates the characteristics of power components and data flow to construct an energy-saving operation model for the 5 G base station. Through optimization, the optimal energy-saving and carbon-reduction strategies for each time period are obtained, thereby promoting energy conservation and emission reduction in 5 G base stations.
1) For energy equipment, the power component characteristic constraints of the 5 G base station units, including the air conditioning load characteristic constraints ((1), (2), (3)), power system characteristic constraints (Eq. (4)), and energy storage system characteristic constraints ((5), (6), (7), (8)).
However, the construction and operation of 5 G base stations face significant energy consumption challenges. Under full-load conditions, the power consumption of 5 G base stations is approximately 3–4 times that of 4 G base stations, which has a notable impact on energy consumption and environmental concerns (Zhang et al., 2020, Feng et al., 2012).
