Abstract: 5G base station uses the same energy control method in different operating states, resulting in lower energy utilization efficiency, which in turn affects the operational performance of 5G base station. To optimize the energy efficiency of 5G base station oil electricity hybrid technology, performance improvement and optimization methods for open-pit mine 5G base station oil electricity hybrid technology are proposed. Calculate the static energy consumption and dynamic energy consumption of 5G base station separately, construct an energy consumption model, and based on the hybrid technology of oil and electricity, build an energy consumption optimization model and constraints with the goal of minimizing base station energy consumption and maximizing economic benefits. Using PSO algorithm solves the constructed optimization model to achieve performance improvement and optimization of 5G base station oil electricity hybrid technology in open-pit mines. The experimental results show that the designed method has an energy efficiency ratio of 0.95 and an average comprehensive benefit ratio of 75.42% in practical applications, which can optimize the energy utilization performance of 5G base station.
