摘要/Abstract

摘要： 压缩空气储能系统被认为是最具发展前景的大规模电力储能技术之一,具有广阔发展前景。本文建立了压缩空气储能系统的技术经济性计算模型,并针对蓄热式压缩空气储能系统应用于工业用户的情景,在有无补贴的两种计算条件下,进行了技术经济性分析。研究结果表明,在无补贴条件下,系统内部收益率为16.3%,投资回收期为9.2年;计算补贴时,系统内部收益率为23.8%,投资回收期为6.2年。同时本文还对该系统进行了盈亏平衡、敏感性等不确定性分析,找出影响系统经济性的敏感因素;并得出政策扶持对提高压缩空气储能电站的财务收益水平和抗风险能力具有重要的作用。本文的研究可以为压缩空气储能系统的研究和工程应用提供理论参考和工程指导。

Abstract: Compressed air energy storage is one of the most promising large scale electrical energy storage technologies. A techno-economic model of compressed air energy storage system is constructed. The techno-economic analysis is carried out under the conditions with and without the subsidy policy of a compressed air energy storage system with thermal energy storage for the scenario of being applied to an industrial plant. The results without subsidy policy indicate that the internal rate of return of this system is 16.3%, and the dynamic investment pay-back period is 9.2 years, and the results with subsidy policy indicate the above evaluation index is 23.8% and 6.2 years. Furthermore, the economical sensitivity factors are illustrated through the uncertainty analysis including the break-even analysis and the sensitivity analysis. In addition, the policy support plays an important role for the lower risk and improve return of the compressed air energy storage power plant. The study of this paper can provide theoretical reference and engineering instruction for the research and engineering application of compressed air energy storage system.

Key words: compressed air energy storage, technological economy, break-even analysis, sensitivity analysis
