“光火储”一体化发电系统的季节适应性分析

SEASONAL ADAPTABILITY ANALYSIS OF INTEGRATED POWER GENERATION SYSTEM OF“PHOTOVOLTAIC THERMAL STORAGE”

为探索基于压缩空气储能的“光火储”一体化发电系统的季节适应性,选取一年内4个典型日分别代表春夏秋冬4个季节,研究季节特性对一体化发电系统5种运行模式的影响。结果表明:季节变化时,一体化发电系统性能变化较大,其中模式2、3性能受季节变化影响最大,模式4不受季节影响但性能较差,模式5季节适应性最好。此外,一体化发电系统可依据实际运行条件灵活选择运行模式,避免能源浪费。

In order to explore the seasonal adaptability of the integrated power generation system of“photovoltaic thermal storage”based on compressed air energy storage,four typical days in a year are selected to represent four seasons of spring,summer,autumn and winter,the influence of seasonal characteristics on the five operating modes of the integrated power generation system are studied.The results show that the performance of the integrated power generation system changes greatly when the season changes.Among them,the performance of mode 2 and mode 3 is most affected by seasonal changes,mode 4 is not affected by the season but the performance is poor,and mode 5 has the best seasonal adaptability.In addition,the integrated power generation system can flexibly select the operation mode according to the actual operating conditions to improve the system efficiency.
