随着5G网络的大规模应用,基站的能耗管理与优化是保证电网运行稳定性的同时,促进新能源电力消纳、优化用户用电行为所采取的行动之一。5G宏基站耗能设备参与需求响应能够在降低基站用电成本的同时为电力系统提供可调节资源。针对不断扩建的5G基站,提出了一种5G宏基站参与需求响应的负荷计算方法,并分析其参与需求响应的潜力。首先分析了基站无线利用率与能耗的关系,对基站通信设备及空调系统建模。其次,考虑通信设备以通道关断方式助力空调负荷参与需求响应的运行模式,并以典型日负荷参与需求响应为例,分析了该模式下基站空调负荷参与需求响应的潜力,仿真结果表明,基站通信设备采用智能通道关断可以增加空调负荷参与需求响应的潜力。

With the widespread application of 5G network,energy management and optimization of the base station is one of the actions taken to ensure the stability of the power grid operation,promote the efficient utilization of renewable energy and optimize the power consumption behavior of the users. The participation of5G macro base station energy-consuming equipment in demand response can provide adjustable resources for the power system while reducing the electricity cost of the base station. A load calculation method of 5G macro base station participating in demand response is proposed, and its potential to participate in demand response is analyzed. The correction between base station radio utilization and energy consumption, models the base station communication equipment and air conditioning system is analysed. Secondly, the operation mode in which the communication equipment contributes to the participation in demand response of the air conditioning load by way of channel shutdown is considered. Using a typical daily load participation in demand response as an example, the potential of air conditioning loads in a 5G macro base station participating in demand response under this operation mode is analyzed. Simulation results show that implementing intelligent channel shutdown on the base station communication equipment can increase the potential of air conditioning load to participate in demand response.
