Abstract： In adiabatic compressed air energy storage（A-CAES） systems，the strong coupling of cold，heat，and electricity during operation leads to trade-offs in their outputs，and the heating capacity is insuficient compared to the power supply capacity. To address high-heating-demand scenarios，two coupled systems—air-supplemented heating （SH-CAES） and heat pump-coupled （HP-CAES）—are proposed to enhance the heating capacity of A-CAES. Based on the power and heating demands of a residential community of 6Oo households，three energy storage systems—A-CAES， SH-CAES，and HP-CAES-with a capacity of 3 MW/22.5 MW ·h were designed. By constructing thermodynamic models for the three systems， their performances under different ambient temperatures， compressor/expander stages，and preheated water flow rates were analyzed and compared. The results show that while meeting power supply requirements， SH-CAES achieves the highest heating efficiency （ HE ）of 98.7% in relatively low-temperature，high-latitude environments， representing a 33.7% improvement over conventional combined heat and power plants （CHTP）. HP-CAES achieves the highest HE of 133.05% in relatively high-temperature，low-latitude environments， representing a 68.05% improvement over CHTP. As the number of compressor stages，expander stages，and preheated water flow rate decrease， the external heat output of both SH-CAES and HP-CAES systems increases. Economic analysis results indicate that in low-latitude regions，the static payback periods for SH-CAES and HP-CAES are shortened by 20.75% and 31.08% ， respectively，compared to A-CAES，and by 43.26% and 52.28% ，respectively，compared to CHTP. This study provides new technical pathways and theoretical references for achieving low-carbon， efficient，and economical regional heating.
