摘要

为有效提高太阳能发电的能源利用率和运行灵活性，提出了一种耦合太阳能光伏、太阳能光热、压缩空气储能的集成系统。在白天，压缩空气储能系统将光伏弃电存储，并将压缩热传递至光热电站；在晚上，压缩空气储能系统释放空气，并采用光热电站的给水加热，从而提高机组的发电负荷。基于系统模拟，对耦合方案进行了热力学分析和经济性分析。分析结果表明：耦合系统光热整体发电效率为41.24%，整体?效率为66.79%；压缩空气储能系统往返效率为72.14%，压缩空气系统?效率为84.30%，均有显著提高；耦合系统白天的调峰深度为7.02%，晚上调峰深度为19.69%；此外，耦合方案的动态回收周期为3.10年，净现值为4 135.06万元，与非耦合系统相比，均表现良好。
