摘要： 5G基站正处于规模化应用的关键时期，高能耗导致的经济性问题是阻碍其发展的因素之一。同时，5G基站通常配备保障供电可靠性的储能电池，其闲置能量为电网提供了灵活可调资源。为降低5G基站功耗，充分利用储能资源，本文首先建立5G基站功耗模型，分析移动用户大量接入对5G基站备用储能可调度能量的影响，其次基于能量边界投影建立备用储能聚合调控模型，然后考虑5G基站运营商参与电能交易建立合作博弈模型并通过交替方向乘子法求解。算例分析结果表明通信负载转移可以有效降低5G基站低负载时期的功耗，增加储能可调度能量，所提分布式优化运行模型能有效实现5G基站等利益主体的互利共赢。

Abstract: 5G base stations are in a critical period of large-scale application, and economic problems caused by high energy consumption are one of the factors hindering their development. At the same time, 5G base stations are usually equipped with energy storage batteries to ensure power supply reliability, and their idle energy provides flexible and adjustable resources for the power grid. In order to reduce the power consumption of 5G base stations and make full use of energy storage resources, this paper first establishes a 5G base station power consumption model and analyzes the impact of a large number of mobile users accessing the 5G base station's backup energy storage and dispatchable energy. Secondly, based on energy boundary projection, a backup energy storage aggregation regulation model is established. The sexual aggregation method is used, and then a cooperative game model is established by considering the participation of 5G base station operators in power transactions and solved by the alternating direction multiplier method. The calculation example analysis results show that communication load transfer can effectively reduce the power consumption of 5G base stations during low load periods and increase the dispatchable energy of energy storage. The proposed distributed optimization operation model can effectively 

achieve mutual benefit and win-win for 5G base stations and other stakeholders.
 

Key words: 5G base station, communication load, backup energy storage, alternating direction method of multipliers
