具有出力不确定性和反调峰特性的可再生能源大规模并网给电力系统调度运行带来了新的挑战。压缩空气储能（ Compressed Air Energy Storage， CAES）系统以其调节速率快、选址灵活、使用寿命长等特点为解决可再生能源利用率低这一难题提供了新的解决思路。特别地，回热式压缩空气储能（ Regenerative CAES， RCAES）系统因可以有效利用压缩过程释放的热量而备受关注。能量转换效率是RCAES系统的重要性能指标，但当前研究集中在系统热力学过程分析上，对其效率评估研究有限。本文从 RCAES 系统的电能-机械能-热能转换过程及基准参数出发，提出了一种RCAES系统效率评估方法。通过某典型RCAES系统设计方案，本文对所提方法进行了详细计算说明，验证了其合理性。

Due to the uncertainty and anti-peaking nature, integration of large scale renewable energy brings great challenges to the operation and dispatch of power systems. CAES ( Compressed Air Energy Storage ) system pro-vides new ideas to solve this problem as its characteristics of fast regulating, flexible location and long service life. Especially, RCAES ( Regenerative Compressed Air Energy Storage) system is widely concerned as its repurposing of the heat released in the compression process. The efficiency of energy conversion is a key indicator of RCAES system. However, current research mostly focuses on the thermodynamic process and few works has been done on the efficiency analysis of the whole RCAES system. Based on the electrical-mechanical-thermal dynamic process and with measurable parameters, we present an efficiency evaluation method of RCAES system in this paper. A typical RCAES design scheme is studied to illustrate and validate the effectiveness of the proposed method.
