压缩空气储能技术可以提高电网的供电能力和稳定性，特别是当波动的可再生能源大量连接时。而将冷、热、电联合系统纳入压缩空气储能系统，可以实现稳定运行和高效利用能源。提出了一种新型的冷热电联产压缩空气储能系统。该系统结合了燃气发动机、辅助热交换器和氨水吸收式制冷系统。热力学和经济目标之间的设计权衡，即，采用进化多目标算法对该组合系统的总火用效率和产品总比成本进行了研究。结果表明，随着火用效率的提高，产品单位总成本在开始阶段受影响较小，而在随后阶段则大幅上升。最佳的权衡解决方案是选择与总火用效率为53.04%，总产品单位成本为20.54美分/千瓦时，分别。决策变量随火用效率的变化表明，压气机、涡轮机和预热涡轮机进气的换热器是经济有效地追求更高火用效率的关键设备。分析还表明，为获得最佳折衷方案，应降低压缩机和回收压缩热和加热压缩空气膨胀的两个换热器的投资成本（尤其是后者），同时显著提高燃气发动机的热力学性能。
Compressed air energy storage technologies can improve the supply capacity and stability of the electricity grid, particularly when fluctuating renewable energies are massively connected. While incorporating the combined cooling, heating and power systems into compressed air energy storage could achieve stable operation as well as efficient energy utilization. In this paper, a novel combined cooling, heating and power based compressed air energy storage system is proposed. The system combines a gas engine, supplemental heat exchangers and an ammonia-water absorption refrigeration system. The design trade-off between the thermodynamic and economic objectives, i.e., the overall exergy efficiency and the total specific cost of product, is investigated by an evolutionary multi-objective algorithm for the proposed combined system. It is found that, with an increase in the exergy efficiency, the total product unit cost is less affected in the beginning, while rises substantially afterwards. The best trade-off solution is selected with an overall exergy efficiency of 53.04% and a total product unit cost of 20.54 cent/kWh, respectively. The variation of decision variables with the exergy efficiency indicates that the compressor, turbine and heat exchanger preheating the inlet air of turbine are the key equipment to cost-effectively pursuit a higher exergy efficiency. It is also revealed by an exergoeconomic analysis that, for the best trade-off solution, the investment costs of the compressor and the two heat exchangers recovering compression heat and heating up compressed air for expansion should be reduced (particularly the latter), while the thermodynamic performance of the gas engine need to be improved significantly.
