Current researches on advanced adiabatic compressed air energy storage (AA-CAES) systems primarily focus on optimizing designs and analyzing performance under off-design conditions based on fixed system structures, with limited attention to system-level optimization involving predefined operational modes. By taking a 300 MW-class asymmetric AA-CAES system featuring four-stage compression and three-stage expansion as the object, a novel variable-pressure (sliding-pressure) operation strategy is proposed, along with a matching design between compression and expansion stages. A quasi-dynamic thermodynamic model is developed to analyze and optimize the full charge-discharge cycle performance under fixed time constraints with sliding-pressure control. The results show that the optimized sliding-pressure mode improves the system’s round-trip efficiency to 73.32%, increases the energy density to 3.404 kW·h/m³, and reduces the required air storage volume to 440 000 m³ (only one-fourth of that under constant-pressure operation). Exergy losses are mainly concentrated in the compressors and turbines, accounting for 40.7% and 29.3% respectively. The isentropic efficiency and heat recovery capability of these components has significant influence on overall performance of the system.

当前针对先进绝热压缩空气储能(AA-CAES)系统的研究多基于既定结构开展优化设计与变工况性能分析,缺乏对运行模式进行预设的系统级优化。以300 MW等级四级压缩/三级膨胀的非对称AA-CAES系统为对象,创新提出滑压运行策略及压缩-膨胀级间匹配设计,构建准动态热力学模型,实现了在固定时间约束下对滑压控制充放电全过程的性能分析与参数优化。结果表明:优化后的滑压模式可将储能效率提升至73.32%,能量密度达3.404 kW·h/m³,所需储气体积缩减至44万m³,仅为定压模式的1/4。系统㶲损主要集中在压缩机和透平,分别占总损失的40.7%和29.3%;设备的等熵效率和热回收能力对整体性能具有显著影响。
