摘要
[目的]数据中心能源系统科学规划能够节能减碳,进而有序实现能耗“双控”和社会“双碳”。然而,现有的规划研究主要针对纯电化学储能,没有考虑氢电耦合的新型存储方式;同时,也少有研究以纯绿色供能为指导,整合源储双侧资源进行规划建模。[方法]基于绿色供用能和氢电耦合的理念,分析电、热、冷多能源流的存储、转换与平衡,从降低成本费用和减少外部能源依赖两个维度,构建出计及光伏发电、氢储能和电化学储能的数据中心能源系统优化配置模型,并辅以算例分析。[结果]算例结果表明:相较于纯电化学储能形式,基于氢电耦合的新型储能形式的规划方案具有更低的经济成本和外部能源依赖,所提模型具有良好的现实匹配度。[结论]文章研究成果可以为数据中心能源系统规划建设提供量化指导,也可助力数据中心实现节能减碳,促进其绿色可持续发展。
[Introduction]Scientific planning of data center energy system can save energy and reduce carbon,and then orderly realize"dual control"for the total energy consumption and energy intensity as well as"carbon peak and neutrality"goals.However,the existing researches on planning mainly focus on pure electrochemical energy storage,without considering the new storage mode of hydrogen and electricity coupling;few studies establish planning models by integrating sources and loads under the guidance of pure green development.[Method]Based on the concept of green energy supply and hydrogen-electric coupling,the storage,conversion and balance of electricity,heat and cold energy streams were analyzed.Further,from the dimensions of reducing costs and reducing external energy dependence,the optimal configuration model of the data center energy system that takes into account photovoltaic power generation,hydrogen energy storage and electrochemical energy storage was constructed,and was verified by case study.[Result]The case analysis shows that compared with the pure electrochemical energy storage,the planning scheme considering the hydrogen-electric coupling storage has lower costs and lower dependence on external energy,and the proposed model can well reflect the reality.[Conclusion]The research results of this article not only provide quantitative guidance for energy system planning of data centers,but also help data centers achieve energy conservation and carbon reduction,ensuring their green and sustainable development.
