摘要(Abstract)：

绝热压缩空气储能技术（A-CAES）可用于可再生能源电力的调峰、调频，是实现“双碳”目标的有效手段。为研究级数、上端差、节流阀后压力等关键参数对系统热力学效率与经济性的影响，实现最低度电成本，构建了基于MATLAB的A-CAES模型，并进行计算。结果表明：在模拟工况范围内，效率随级数、上端差的增加而降低，随节流阀后压力的增加而增加，效率最高可达70%以上；二级压缩、二级膨胀的度电成本最低，为0.0413～0.045 0美元/(kW·h)；度电成本随节流阀后压力的增大而减小；当上端差大于2.5 K时，度电成本随上端差的增大而增大。因此，A-CAES可实现高效、低成本储能。

关键词(KeyWords)： A-CAES;效率;度电成本;上端差;节流阀后压力
