摘要
采用热经济学分析方法对超临界压缩空气蓄能系统与压缩空气蓄能系统(CAES)的经济性进行分析。系统输入电能以大工业110 kV低谷电价0.309 9元/(kW.h)和燃气价格为2元/m3为例进行计算,利用EES软件进行模拟。结果表明:超临界压缩空气蓄能系统较CAES更为经济有效,可以达到调节电网负荷的目的,且可以提高可再生能源(如风能、太阳能)发电系统的效益。
By using a thermo-economic analytic method,the cost-effectiveness of a compressed air energy storage system（CAES） and a supercritical one was analyzed.With the electric energy input to the system being the low valley 110 kV electric power for large-scale industries at a price of RMB 0.3099 yuan/（kW·h） and fuel gas price of RMB 2 yuan/m3 serving as an example,a calculation was performed with a simulation being conducted by using the software EES.It has been found that compared with the compressed air energy storage system,the supercritical one is more economic and effective.It can achieve the aim of regulating the load of an electric grid and enhance the economic benefit of a renewable energy source（such as wind and solar energy） power generation system.
