摘　　要：研究储能装置在系统稳态时作为负荷平衡应用——延缓配电网升级——的可能性,量化储能技术收益,给出储能单元的功率和能量计算方法,并结合实际算例讨论储能装置安装地点的选择及其对线路损耗的影响.分析储能装置应用于配电网升级延缓时需要注意的几个重要问题,对于储能技术在电力系统中的应用具有重要的指导意义.This paper discusses the possibility of energy storage devices as load balancing application, which is delaying utility investments in distribution network upgrades. The benefit of the distribution network capacity deferral value is quantified, and power and energy capacities for electricity energy storage systems are estimated. A practical system is utilized to evaluate the proposed methodology, and the siting of energy storage devices and its impact on the network loss are discussed. Finally, some important aspects of the application are analyzed. The main intention is to contribute to the development of methodologies that help understanding the role of energy storage in a distribution system.
