Analysis on Parameter Sensitivity of Electro-Electrical Conversion Efficiency of Compressed Air Energy Storage System

压缩空气储能是在燃气轮机技术的基础上发展起来的一种大型储能技术,是目前除了抽水蓄能之外技术最为成熟的物理储能,如何提高压缩空气储能系统的转换效率,进一步降低储能的成本,是目前研究的重点方向。通过热平衡仿真软件EBSILONProfessional,建立了压缩空气储能系统热力系统模型,对影响压缩空气储能系统电-电转换效率的主要参数进行了敏感性分析,给出了参数优化的方向和建议。

Compressed air energy storage is a large-scale energy storage technology developed on the basis of gas turbine technology,and is currently the most mature physical energy storage technology in addition to pumped-hydro energy storage.How to improve the conversion efficiency of compressed air energy storage system and further reduce the cost of energy storage is the focus of current research.This paper first uses the thermal balance simulation software EBSILON Professional to establish a thermal system model for compressed air energy storage system,and then makes analyses on the sensitivity of the main parameters that affect the electro-electrical conversion efficiency of compressed air energy storage system.Finally,the paper provides the direction and suggestions for parameter optimization.
