First datasets for the CTR-CC-900 configuration

Dataset with the first results from the annual simulation of the configuration CTR-CC-900. The configuration is an evolution of the ones presented in the papers "A Rovira et al. Towards high solar contribution in hybrid CSP-combined cycle gas turbine plants. Int J of Energy Res, 2023, 8289873, DOI: 10.1155/2023/8289873" and "A Rovira et al. Increasing the flexibility and feasibility of concentrated solar power plants by the addition of a low temperature energy storage system. Results in Engineering 25 (2025) 104121. DOI: 10.1016/j.rineng.2025.104121". In particular, the solar field feeds a solarized gas turbine and the exhaust gases coming from the turbine outlet are used to heat up the molten salts of the thermal energy storage system, introducing thus an additional power cycle that increases the power rate of the plant. For the hybrid configuration, there are results for both the base case without solarised gas turbine and for the cases with the solar GT working at 800 ºC, 850 ºC, 900 ºC, 950 ºC and 1000 ºC, and maintaining the size of the solar field but not its efficiency, that decreases with the working temperature. Thus, the nominal thermal power of each central tower receiver decreases from 300 MWth to 290-287-284-281-279 MWth, respectively. The results show an decrease of the solar contribution from 427 GWh yearly (base case) to 426 GWh (800 ºC), 410 GWh (850 ºC), 380 GWh (900 ºC), 341 GWh (950 ºC) and 295 GWh (1000 ºC). For the solar-only configuration, the results are the analogous but varying from 472 GWh to 433-409-376-337-289 GWh for the corresponding base case and the different working temperatures.本数据集包含构型CTR-CC-900的年度模拟初步结果。 该构型是对两篇已发表论文中所提出构型的迭代优化：其一为A Rovira等人发表于《国际能源研究期刊》（*Int J of Energy Res*）2023年的《面向混合聚光太阳能热发电（Concentrated Solar Power, CSP）-联合循环燃气轮机电厂的高太阳能贡献方案》，DOI: 10.1155/2023/8289873；其二为A Rovira等人发表于《工程研究成果》（*Results in Engineering*）2025年第25卷的《通过增设低温储能系统提升聚光太阳能电厂的灵活性与可行性》，DOI: 10.1016/j.rineng.2025.104121。具体而言，本构型的太阳能场（solar field）为太阳能适配型燃气轮机（solarized gas turbine）供能，同时利用燃气轮机排气余热加热熔盐储能系统（molten salt thermal energy storage system）中的熔盐，由此新增一套功率循环以提升电厂总出力。 针对该混合构型，本次研究包含两类工况：一是未搭载太阳能适配型燃气轮机的基准工况，二是太阳能燃气轮机（solar GT）分别在800℃、850℃、900℃、950℃及1000℃下运行的工况。所有工况均保持太阳能场规模不变，但运行温度升高会导致太阳能场效率下降，因此每个中心塔式接收器（central tower receiver）的额定热功率依次从300 MWth（兆瓦热功率）降至290、287、284、281、279 MWth。仿真结果显示，年度太阳能贡献量从基准工况的427 GWh（吉瓦时）依次降至800℃工况的426 GWh、850℃工况的410 GWh、900℃工况的380 GWh、950℃工况的341 GWh及1000℃工况的295 GWh。 针对纯太阳能构型，本次研究得到了类似规律的结果：基准工况年度太阳能贡献量为472 GWh，对应不同运行温度的工况依次为433、409、376、337、289 GWh。
