摘　　要：在分布式能源系统中引入冷热量存储技术,可以很大程度上避免由于用户冷热电负荷的波动性和不同步性造成的供需不匹配问题,并能有效提高能源综合利用水平。文章综述了冷热量存储技术在分布式能源系统中的应用,归纳讨论了主要的冷热量存储方法及其蓄能材料,对其主要技术特点进行分析对比;并从装置容量、系统流程、蓄能温度、运行策略和适用建筑等五个角度总结了引入冷热量存储装置的分布式能源系统的设计优化方法;提出了下一步研究的可能方向。为蓄能型分布式能源系统在蓄能材料上的选择、系统的设计与运行提供一定的参考。The incorporation of cool and heat storage( thermal energy storage-TES) to distributed energy systems(DES) can largely avoid the supply and demand imbalance caused by the fluctuation and asynchronization of users ’ cooling, heating and power loads, and can effectively improve the energy efficiency. This paper reviews the application of TES technology in DES. The main TES methods and TES materials that have been used in DES are discussed, and their main technical features are analyzed and compared. The design optimization methods incorporating TES to DES are summarized including five aspects of storage device capacity, system flow, thermal storage temperature, operation strategy and applicable buildings. The potential directions for further research are proposed. This paper provides some reference including the selection of TES materials and system design and operation for DES with TES.
