摘要(Abstract):
“双碳”目标对数据中心提出了高效率、高可靠、低碳排放的需求。因此,构建了一种接入可再生能源和大规模储能的数据中心全直流供电系统,并对其进行了综合评价。首先,分析数据中心供电系统“源-网-荷-储”各环节的特点和需求,综合考虑系统效率、可用性、经济性、环保性4个维度,建立了评价指标体系。然后,利用AHP(层次分析法)和模糊综合评价法,开发了DCES(数据中心能源系统)架构评价工具。最后,通过DCES将全直流供电系统与传统交流供电系统进行对比评价,结果表明,提出的全直流供电系统尽管经济性稍差,但综合评价指标更优,可作为未来数据中心新型供电系统的一个可选方案。
The “dual carbon” goals have set forth demands for data centers to be efficient, reliable, and have low carbon emissions. Consequently, a full DC power supply system, incorporating renewable energy sources and largescale energy storage, was constructed and comprehensively evaluated. Firstly, the characteristics and requirements of each link of “source-network-load-storage” in the power supply system were analyzed. Taking account of system efficiency, availability, economy, and environmental friendliness, an evaluation indicator system was established.Subsequently, a DCES(data center energy system) architecture evaluation tool was developed using the analytic hierarchy process(AHP) and fuzzy comprehensive evaluation method. Finally, through DCES, a comparative evaluation was performed between the full DC power supply system and the conventional AC power supply system. The results indicate that although the proposed full DC power supply system may have slightly inferior economic performance, its overall evaluation indicators are superior, making it a viable option for the future new power supply system in data centers.
