Analysis and design of the wind-PV-storage hybrid system in"near-zero carbon"data center

随着社会数据信息总量的快速增长,信息通信领域数据中心能耗及碳排放量不断上升。基于“双碳”战略下的绿色发展与低碳转型理念,数据中心开始对绿电使用比例及绿色算力供应提出更高的要求。本文探究了基于风光储供电模式建设“近零碳”数据中心的可行性,通过分别建立风机、光伏阵列、电池储能的输出特性模型,结合全生命周期度电成本的概念进行了数据中心绿色电力的优化配置研究,通过成本分析,得出长项目周期下风光储协同供电系统的度电成本可以趋近于市电价格的结论。本文提出的优化配置方法可以为未来绿能低碳数据中心的建设与设计提供参考。

With the rapid growth in the total amount of social data information,energy consumption and carbon emissions of data centers in the information and communication sector are continuously increasing.Based on the"dual carbon"strategy of green development and low-carbon transformation,data centers are now facing higher demands for the proportion of green electricity used and the supply of green computing power.This paper explores the feasibility of constructing"near-zero-carbon"data centers based on a wind-solar-energy storage power supply model.By establishing output characteristic models for wind turbines,photovoltaic arrays,and battery storage,while combining the concept of the full lifecycle electricity cost,this study conducts optimization research on green power for data centers.The cost analysis concludes that,over a long project period,the cost per unit of electricity for a wind-solar-energy storage collaborative power supply system can approach the price of grid electricity.The optimization configuration method proposed in this paper can provide references for the construction and design of future green energy low-carbon data centers.
