摘要 5G网络高能耗特点会降低传统变电站规划方案的经济性,如何实现5G时代下的绿色通信并兼顾变电站规划的经济性与可靠性亟待研究。该文采用基站休眠策略提升5G网络能效,基于通信负载分布情况动态划分5G基站储能容量,建立兼顾通信负载服务质量及基站供电可靠性的5G网络用电需求模型。在此基础上,盘活5G基站冗余储能参与电网故障不确定情况下的变电站供区故障供电及负荷削峰填谷两种需求响应,提出一种考虑5G网络用电需求及可靠性的变电站双Q规划法。算例分析表明,该文所提的变电站规划方法可在绿色通信下有效地降低变电站的投资成本,基站冗余储能可在电网故障不确定情况下不同程度地改善变电站供区内的失负荷值,提升变电站规划区域的可靠性,适用于5G基站的规模化应用。

Abstract:The large-scale application of 5G base stations can provide high-quality technical support in expanding channel capacity and promoting smart grid construction.5G network not only provides technical support for the transformation and upgrading of substations, but also represents the emerging high-energy consumption power load in the substation supply area. Therefore, it is necessary to consider its power demand during substation planning in the future. Substation planning is faced with such a challenge, that is, to design a double Q planning scheme that takes into account both quantity and quality while reducing the total planning cost. At present, there are few studies on substation location planning for 5G network electricity demand. If the actual peak power consumption of 5G network is used as the basis for substation planning, it will lead to high investment cost and low utilization of substation capacity. It is necessary to further explore substation planning methods that adapt to the large-scale application of 5G base stations and take into account both economy and reliability.
This paper takes into account the economy and reliability of substation planning, and proposes a double Q planning method for substation considering the power demand of 5G network and reliability. Firstly, the energy saving potential of 5G network is analyzed, and the energy efficiency index of 5G network is established. Then, the power demand of 5G network is analyzed from two aspects: the load power consumption after optimizing the energy efficiency of 5G network and the backup power consumption of 5G base station. The energy efficiency optimization model of 5G network is designed based on the base station sleep strategy. The standby energy storage and adjustable energy storage of 5G base station are quantified according to the spatial and temporal distribution of communication load. The standby energy storage supplies power to the base station when the power grid is faulty to ensure the reliability of the power supply of the base station. The energy storage can be regulated to participate in peak cutting and valley filling when the power grid is faulty, and also participate in fault power supply when the power grid is faulty to improve the reliability of the supply area of the substation. Finally, the double Q planning method of substation is transformed into the substation planning problem considering the electricity demand of 5G network and the opportunistic constraint regulation problem of base station energy storage under different reliability confidence in the substation supply area, so as to achieve the double Q goal of substation planning.
Through the analysis of numerical examples, the practicability and effectiveness of the proposed double Q programming method for substation planning are verified, and the following conclusions are drawn: The energy efficiency of 5G network is optimized by executing the sleep strategy for the micro-base station. Although the overall power consumption of 5G network is reduced, the quality of service of communication load is guaranteed. The storage capacity of 5G base station is reserved to ensure uninterrupted power supply for the base station in case of power grid failure, and the power supply reliability of the base station is guaranteed. Activate redundant energy storage of base station to respond to power grid demand, participate in fault power supply, peak cutting and valley filling for profit, and realize mutual benefit and win-win between power grid and communication operators. The economy and reliability of substation planning are guaranteed.
