摘要：

5G基站的电费成本已经成为阻碍5G通信技术发展的因素.通过盘活5G基站储能资源,以实现降低5G基站用电成本的目的.首先建立考虑通信负载的5G基站负荷模型和考虑5G基站对储能备用电量需求与配电网供电可靠性的5G基站储能容量可调度模型;提出了一种针对5G储能调度的充放电策略;建立了5G基站储能参与配电网协同优化调度的模型.通过不同方案对5G基站储能优化调度的经济性进行对比.算例分析结果表明,将5G基站闲置储能参与配电网统一优化调度,可在降低5G基站的用电成本的同时,缓解配电网供电压力,提高系统内新能源消纳率,实现通信运营商与电网之间的双赢.

Abstract:

The electricity cost of 5G base stations has become a factor hindering the development of the 5G communication technology. This paper revitalized the energy storage resources of 5G base stations to achieve the purpose of reducing the electricity cost of 5G base stations. First, it established a 5G base station load model considering the communication load and a 5G base station energy storage capacity schedulable model considering the energy storage backup power demand of the 5G base station and the power supply reliability of the distribution network. Then, it proposed a 5G energy storage charge and discharge scheduling strategy. It also established a model for 5G base station energy storage to participate in coordinated and optimized dispatching of the distribution network. Finally, it compared the economy of optimized dispatch of 5G base station energy storage of different schemes. The analysis results show that the participation of idle energy storage of 5G base stations in the unified optimized dispatch of the distribution network can reduce the electricity cost of 5G base stations, alleviate the pressure on the power supply of the distribution network, increase the rate of new energy consumption in the system, and realize a win-win situation between the communication operator and the grid.

Key words: 5G base station, energy storage, distribution network, renewable energy, optimal scheduling
