摘要
随着数据中心能耗持续攀升,传统UPS系统在能效优化与电网交互方面面临严峻挑战。文章通过构建储能型不间断电源系统(energy storage type of UPS,EUPS)交直流混合架构,提出分层控制策略与多模式储能优化方案,解决了铅酸电池容量衰减、双变换拓扑能效瓶颈及动态响应迟滞等问题。在30kVA负载条件下,EUPS系统可实现±0.05Hz的电网频率精准调节,动态响应时间缩短至200ms,并通过峰谷策略使系统能效提升8%~12%。本文提出的集成化改造方案为存量数据中心能效升级提供了经济可行的技术路线,其双向能量交互特性为构建源网荷储一体化新型电力系统提供参考。
With the continuous increase in energy consumption of data centers,traditional UPS systems face severe challenges in energy efficiency optimization and grid interaction.By constructing the AC/DC hybrid architecture of the energy storage type of UPS(EUPS)system,this article proposes a layered control strategy and multi-mode energy storage optimization scheme,which solves the problems such as capacity degradation of lead-acid batteries,energy efficiency bottleneck of dual transformation topology,and dynamic response delay.Under a 30kVA load condition,the EUPS system can achieve precise adjustment of the grid frequency within±0.05Hz,shorten the dynamic response time to 200ms,and improve system energy efficiency by 8%~12%through peak valley strategy.The integrated transformation scheme proposed in this article provides an economically feasible technical route for upgrading the energy efficiency of existing data centers,and its bidirectional energy interaction characteristics provide a reference for building a new type of integrated power system with source-grid-load-storage.
