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 large-scale 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 hi-erarchy process(AHP)and fuzzy comprehensive evaluation method.Finally,through DCES,a comparative evalua-tion was performed between the full DC power supply system and the conventional AC power supply system.The re-sults indicate that although the proposed full DC power supply system may have slightly inferior economic perfor-mance,its overall evaluation indicators are superior,making it a viable option for the future new power supply sys-tem in data centers.
