摘要

目的

空压站提供工业生产所需压缩空气，是工业领域主要的高耗能设施之一。为了节省空压站运行的电费成本，结合工商业分时电价政策，提出了一种将双工质气体压缩储能与空压站相结合的供气系统，构建储能型空压站。

方法

运用双工质气体压缩储能技术，将储气库的工作压力设置为供气压力，谷电压缩空气、峰电释放压缩空气，通过CO

储能回路的协同运行实现压缩空气的储存与释放。针对大型工业空压站的气量需求和运行工况，设计了基于该技术的供气系统，并开展了热力学计算和技术经济性分析。

结果

结果表明：按当量电能换算，系统储能效率约为 81%，接近锂电池的储能效率。按浙江省分时电价政策，系统可实现每日两次谷电储能和峰电释能的循环，项目采用峰谷电价差套利方式运行，静态投资回收期约为 4.8 a。

结论

基于双工质气体压缩储能的供气系统可灵活部署于工业企业中，并与空压站协同运行，具有储能效率高、经济效益好等优点，具备良好的工程可行性。未来，随着电力市场化改革的不断推进，此类系统有望成为独立储能设施，或作为电网侧储能的补充形式。

Abstract

Objective

Air compression stations provide compressed air for industrial production and are among the major high energy-consuming facilities in industry. To reduce electricity costs

and in conjunction with the time-of-use electricity pricing policy for industrial and commercial sectors

a compressed air supply system integrated with binary gas compression energy storage was proposed

forming an energy-storage-based air compression station.

Method

The binary cycle gas compression en

ergy storage technology was adopted

with the working pressure of the gas storage tank set equal to the compressed air supply pressure. Compressed air was stored during off-peak (valley) periods and released during peak demand periods

with the carbon dioxide energy storage loop operating in coordination to complete the storage and release cycle. Based on the gas consumption and operating conditions of large-scale industrial air compression stations

the system was designed

and thermodynamic calculations as well as techno-economic analyses were carried out.

Result

The results show that

when converted into equivalent electrical energy

the system achieves an energy storage efficiency of approximately 81%

which is close to that of lithium iron batteries. According to Zhejiang Province's time-of-use electricity pricing policy

the system can operate on a twice-daily cycle of off-peak charging and peak discharging. The project operates through peak-valley electricity price arbitrage

with an estimated static investment payback period of about 4.8 years.

Conclusion

The compressed air supply system based on binary cycle gas compression energy storage can be flexibly deployed in industrial enterprises and integrated with air compression stations. It features high energy storage efficiency

good economic performance

and strong engineering feasibility. In the future

with the ongoing advancement of electricity market reforms

this type of system may serve as an independent energy storage solution or as a supplement to grid-side storage.
