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。

Abstract

In order to effectively improve the energy efficiency and operational flexibility of solar power generation

an integrated system coupling solar photovoltaic

solar thermal and compressed air energy storage is proposed.During the day

the compressed air energy storage system will store the photovoltaic abandoned power

and transfer the compression heat to the photothermal power station. At night

the compressed air energy storage system releases air and uses water supply of the photothermal power station to heat up

thereby increasing the power generation load of the unit. Based on the system simulation

the coupling scheme is analyzed thermodynamically and economically. The overall generation efficiency of the coupled system is 41.24%

while the overall exergy efficiency is 66.79%. The round-trip efficiency of the compressed air energy storage system is 72.14%

while the exergy efficiency of the compressed air system is 84.30%

both of which have increased significantly. The peaking depth of the coupled system is 7.02% in the daytime and 19.69% in the evening. In addition

the dynamic recovery cycle of the coupling scheme is 3.10 years

and the net present value is 41.350 6 million yuan.
