发展基于微型先进绝热压缩空气储能系统(Advanced Adiabatic Compressed Air Energy Storage, AA-CAES)的分布式冷热电联产(Combined Cooling, Heating and Power, CCHP)系统是构建绿色能源体系的关键部分。本文基于微型AA-CAES的CCHP系统为对象建立了热力学与经济学模型，对压缩机压比递减系数、透平机膨胀比递减/递增系数以及释能阶段换热器上端差4个关键参数进行敏感性分析。在设计条件下，系统储能效率达到47.12%，发电成本与利润率分别为166.3 $/(MW?h)和47.2%。敏感性分析表明，压缩机压比递减系数对发电成本与利润率影响较低，而膨胀比递减系数增加对系统储能效率以及利润率造成的负面影响较为显著。减小释能阶段换热器上端差能同时提高储能效率与利润率。

Developing a distributed combined cooling, heating, and power (CCHP) system based on a micro advanced adiabatic compressed air energy storage (AA-CAES) system is a key part of building a green energy system. This paper establishes thermodynamic and economic models for a micro AA-CAES-based CCHP system and conducts sensitivity analyses on four key parameters: the compressor pressure ratio decrement coefficient, the turbine expansion ratio decrement/increment coefficient, and the upper temperature difference of the heat exchanger during the energy release phase. Under design conditions, the system achieves an energy storage efficiency of 47.12%, with a power generation cost of 166.3 $/(MW?h) and a profit margin of 47.2%. The sensitivity analysis shows that the compressor pressure ratio decrement coefficient has a relatively low impact on power generation cost and profit margin, while an increase in the expansion ratio decrement coefficient significantly negatively affects system energy storage efficiency and profit margin. Reducing the upper temperature difference of the heat exchanger during the energy release phase can simultaneously improve energy storage efficiency and profit margin.
