中文摘要：

针对工业园区综合能源系统的削峰问题，建立将蓄冷空调系统用于削峰的优化规划模型，提出采用临界运行电价和经济平衡电价分别作为蓄冷空调系统运行经济性与规划经济性的度量。进而根据经济平衡电价确定规划时的最优蓄冷容量，进一步确定相关的设备容量。然后对冰蓄冷系统和水蓄冷系统进行经济性对比与分析，为决策者提供选择蓄冷类型的经济依据。最后以某工业企业的空调系统改造为水蓄冷空调系统作为算例，计算相应的经济平衡电价、最优蓄冷容量和相关设备容量，并验证最优蓄冷容量的正确性。

英文摘要：

An optimal planning model of CSS（Cold-Storage air-conditioning System） for the peak load reduction of integrated energy system in industrial park is built,which applies the critical operational electricity price and the economic equilibrium electricity price as the indexes to evaluate the operational economy and the planning economy of CSS respectively. The economic equilibrium electricity price is used during the planning to determine the optimal cold-storage capacity and the related equipment capacities. Comparison between ice-storage system and water-storage system is carried out to provide the economic basis for decision makers during the cold-storage type selection. As an example,the economic equilibrium electricity price,the optimal water-storage capacity an air-conditioning system retrofitting project of an cold-storage capacity is verified. and the related equipment capacities are calculated for industrial enterprise ,and the correctness of the optimal cold-storage capacity is verified.
