摘要
随着互联网数据中心IDC的快速发展,为其配备的不间断电源系统UPS规模越来越大,由于UPS的电池系统只有在少数的停电时段应用,造成了大量的资源闲置.在保证备电的前提下,充分挖掘UPS中电池系统的储能功能,是一种经济高效的储能形式.在常规UPS的基础上,提出了储能型不间断电源系统(energy storage type of UPS,EUPS)的实现架构,EUPS多种"备电+储能"应用功能的控制策略,以及EUPS参与电网多场景调节的协调控制策略.最后,基于建成的EUPS示范系统,验证了所提的EUPS系统架构和控制策略的有效性.
Abstract
With the rapid expansion of internet data centers(IDCs),the deployment of uninterruptible power supply(UPS)systems in IDCs has seen significant growth.Despite their critical role,UPS battery systems remain largely underutilized,being active only during infrequent power outages.This paper advocates for the enhanced utilization of the energy storage capabilities of UPS battery systems,promoting an economical and efficient approach to energy management without compromising backup power reliability.We introduce an advanced architecture for energy storage type of UPS(EUPS),delineate control strategies for its diverse energy storage applications,and present a framework for its integration into multiscenario power grid regulations through coordinated control strategies.The efficacy of the proposed EUPS system architecture and control methodologies is substantiated through a fully operational EUPS demonstration system.
