太阳能烟囱是一种理想的绿色能源生产系统，特别适用于沙漠地区。由于伊朗科尔曼地区的太阳辐射强度很高，可以认为是使用这种能源的潜在地区。使用太阳能烟囱的一个缺点是夜间效率低。在这项研究中，设计了一种新的优化配置，以同时发电和制热。对于连续供电，考虑的组合提供了良好的效果，而在夜间，可以通过固体氧化物电解槽产生氢气并由固体氧化物燃料电池将其转换为电能来提供备用能量。然后，采用流体搜索优化算法生成最优经济系统。余热锅炉压力和气室长度的影响分别为3.21%和21.17%。忽略其他参数的影响。实验结果表明，在迭代和70次迭代的情况下，FSO和NSGA-II都达到了有效值，其中FSO的最优值为27,527,116,953美元。这表明所设计的配置在夏季比冬季能更好地满足需求，冬季需要更多的备用储能。
Solar chimney is one of the ideal green energy production systems which can be used especially in desert areas. Due to the high radiation of solar intensity in the Kerman area of Iran, it can be considered as a potential region for employing this kind of energy. One drawback of using the solar chimney is its low efficiency in the night time. In this study, a new optimal configuration is designed to generate both electricity and heat simultaneously. For continuously supplying the electricity, the considered combination gives good result while at night time, the backup energy can be supplied by generating the hydrogen with a solid oxide electrolysis cells and converting it to the electricity by solid oxide fuel cells. Afterward, a fluid search optimization algorithm is employed for generating an optimal economic system. The impact of the pressure of HRSG and the length of the cells are 3.21% and 21.17%, respectively. The effect of the other parameters is ignored. Experimental results showed that the efficient value for FSO and NSGA-II are achieved in 64 and 70 iterations and the optimal value belongs to FSO with 27,527,116,953 $ which shows using the designed configuration can better supply the demand properly in the summer than the winter and in the winter, there is more need to use the backup stored energy.
