摘要
储能是保证数据中心高效、低碳、安全、智能供能的重要保障,如何更加合理地为数据中心配置储能,得到越来越多的关注.本文分析了储能在数据中心的作用,梳理了可用于数据中心储能的铅酸电池、铅炭电池、锂电池、飞轮储能、相变储能、卡诺电池储能、CO2 热泵储能的工作原理、系统布置、运行策略,给出了数据中心储能系统的配置方式.提出数据中心储能将向与可再生能源深度融合、电热冷联储联用、替代备用发电机组、从负荷侧转变为供电侧获取收益、应用新型储能技术等方向发展.
Abstract
Energy storage is a critical guarantee for ensuring efficient,low-carbon,safe,and intelligent power supply in data centers.There is increasing attention on how to more reasonably configure energy storage for data centers.This paper analyzes the role of energy storage in data centers and reviews the working principles,system arrangements,and operating strategies of various energy storage technologies applicable to data centers,including lead-acid batteries,lead-carbon batteries,lithium batteries,fly-wheel energy storage,phase change energy storage,carnot battery storage,and CO2 heat pump storage.It provides configuration methods for data center energy storage systems.The paper proposes that the fu-ture development of energy storage in data centers will focus on deep integration with renewable energy,combined heat and power storage,replacement of backup generators,transitioning from load-side to supply-side for profit generation,and the application of new energy storage technologies.
