In this paper, modeling and analysis of a hybrid solar power plant are presented. Within a theoretical framework, thermodynamic modeling of several components of the cycles has been conducted through simultaneous consideration of energy, exergy, and emissions. The energy and exergy of the combined cycle of the solar-gas turbine and organic Rankine cycle (ORC) have been investigated. Heat loss from the solar receiver has been studied considering essential factors such as wind speed, air pressure, and ambient temperature. The emissions, mass flow rate of working fluids, pressure ratio, and concentration ratio are evaluated and compared with a standard fossil-fueled power plant. The results show that the energy efficiency and exergy of the overall system are substantially improved as the solar radiation intensity increases. Furthermore, the output power of the ORC is reported to be higher than that of the Rankin steam cycle. Consequently, when solar energy is used, the carbon dioxide emission is reduced by 150%.

本文介绍了混合太阳能发电厂的建模和分析。在理论框架内，通过同时考虑能量，火用和排放，对循环的几个组成部分进行了热力学建模。研究了太阳能燃气轮机和有机朗肯循环（ORC）联合循环的能量和火用。考虑到诸如风速，气压和环境温度等基本因素，研究了太阳能接收器产生的热量损失。评估排放，工作流体的质量流量，压力比和浓度比，并将其与标准化石燃料发电厂进行比较。结果表明，随着太阳辐射强度的增加，整个系统的能效和火用显着提高。此外，据报道，ORC的输出功率高于兰金蒸汽循环的功率。因此，当使用太阳能时，二氧化碳排放减少了150％。
