摘　　要：为了研究冷热电联供与水蓄能耦合利用,将冷、热、电三联供及蓄能耦合的分布式能源系统应用于上海某会展及商业综合区域。通过负荷计算及供能成本分析,确定了"以热定电"的系统配置,在允许上网的政策下,综合考虑能源利用效益及经济效益,推荐采用"三联供优先、按需蓄热(冷)、按需发电及供热(冷)、自发自用、热(冷)电平衡"的供能策略,并以冬、夏季典型日为例,得到供能系统使用顺序及能量平衡图。In order to study CCHP storage coupled with the use of water. Based on the CCHP（ combined cooling,heating power） coupled with energy storage,a type of distributed energy system was applied in an exhibition and commercial area in Shanghai. The system configuration mode of ＂thermal demand management（ TDM） ＂was confirmed via the calculation of cooling,heating load and the analysis of operation costs. With the support of policy,i. e. the CCHP system is permitted to export electricity to the electric grid. Proper operation strategies were recommended,including＂CCHP prior,storage heat（ cold） according to the demand,produce thermal and electric load according to the demand,balance thermal and electric load＂,which are of economic potential and more effective. Two typical days were set as exauples in summer and winter respectively to analyze the priority in order for energy supplying,as well as the energy equilibrium diagrams for typical days were described schematically.
