Performance analysis of peak load balancing for compressed air energy storage assisted solar power station
摘要
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.关键词
