摘要：Energy storage technology is an efficient way to solve the discontinuous and unpredictable of renewable energy. This paper combined isobaric CAES with low grade waste heat to reduce the pollution of CAES and avoid the exergy destruction in throttling process. The thermodynamic analysis including energy analysis and exergy analysis, was conducted to evaluate the performance of the proposed system. The results show that total round trip efficiency of the proposed I-CAES can be improved nearly 11% and the effective air storage density increases 37.6% compared with the conventional CAES. Meanwhile, a parametric analysis is also conducted to evaluate the effects of several key parameters on the system performance.
