摘　　要：为解决冰蓄冷空调系统的运行调度问题,提出两阶段优化调度的策略。第一阶段对机组能耗模型进行合理简化,以系统当日整体运行费用最低为优化目标,建立混合整型二次规划模型,并求出可接受的初解。第二阶段采用调度后处理的手段,以提升系统连续运行稳定性和经济性为目标,通过调整冷水机组的逐时运行数量和负载率对初解进行优化,使最终的调度结果符合现场实际运行需求。工程实例分析结果表明,采用此种调度策略,可实现降低系统当日整体运行费用的同时,减少设备启停次数,避免设备频繁启停导致系统波动,满足现场运行需求。In order to solve the operation scheduling problem of ice storage air-conditioning system,a two-stage optimization scheduling strategy is proposed.In the first stage,the chiller energy consumption model is reasonably simplified,and taking the lowest overall operating cost of the system on the day as the optimization goal,a mixed integer quadratic programming model is established and an acceptable initial solution is obtained.In the second stage,the postdispatching method is adopted to improve the continuous operation stability and economy of the system.The initial solution is optimized by adjusting the hourly operation number and load rate of the chiller,so that the final scheduling result meets the actual operation demand.The actual engineering analysis results show that the use of the scheduling strategy in this paper can reduce the overall operating cost of the system on the day,while reducing the frequency of chiller start and stop,avoid frequent start and stop of the chiller cause system fluctuations,and meet the actual scheduling requirements.
