摘　　要：充分挖掘算力中心中蕴含的负荷灵活性是实现算力电力协同的关键。文章聚焦于算力中心内部通信高压直流电源(high voltage direct current,HVDC)侧储备一体电池的闲置灵活性,提出了一种高溢价应用场景:一方面,提升列头柜的算力需求承载量,从而获得高溢价应用;另一方面,同时考虑向电网提供负荷侧灵活性,以获得电力辅助服务市场补偿并降低电费。文章阐述了该应用场景的原理,并对不同情境下的价值评估进行了讨论,以为HVDC侧储备一体电池的闲置灵活性调控提供理论依据。最后,展望了未来算力电力协同发展的路径。Exploiting inherent load flexibility within data centers is key to achieving synergy between computing power and electricity.This study focuses on the idle flexibility of integrated backup and energy storage batteries on the side of high-voltage direct current(HVDC)communication power supplies in data centers.An application scenario for this idle flexibility,which enhances the supported workload of cabinets to achieve premium applications,is proposed.Meanwhile,it simultaneously provides load flexibility to the grid to obtain compensation from electricity ancillary service markets and reduce electricity costs.Specifically,this study presents the principle for this application scenario and discusses the value assessment under different scenarios,providing a theoretical foundation for determining the idle flexibility of HVDC-side integrated energy storage and backup batteries.Finally,prospects for exploring the synergy between computing power and electricity are discussed.
