In the last decades, there is an increasing attention on renewable energy sources to overcome energy related problems such as global warming/climate change, security of energy supply, depletion of fossil fuels, unpredictable energy prices, conflictions on energy sources etc. Solar energy is an abundant source of renewable energy readily available on the earth. With the recent developments in solar energy conversion technologies, concentrating solar power (CSP) systems for heat and power productions have become attractive solutions. Currently, CSP systems using parabolic trough collectors (PTCs) are dominated the global CSP market since there are the most mature technology and the most installed CSP systems in the world. Turkey is one of the countries benefiting from good solar radiation, so CSP systems may be one of the solutions for the renewable energy production. In this study, technoeconomic analysis of a small (1 MWe) PTC-CSP power plant using combined Rankine cycle for electricity production in Izmir, Turkey, is presented as a case study for an example of PTC-CSP power plant utilization in the locations in Turkey with high solar radiation values. Levelized cost of electricity (LCOE), internal rate return, net present value and payback period of the power plant for three different layout configurations of the PTCs in the solar field are calculated by using System Advisory Model (SAM), MATLAB and Excel softwares. The results show that for 1MWe PTC-CSP power plant in İzmir, the initial investment cost is approximately 3.9 Million USD with LCOE of 135 USD/MWh, and the annual operational cost of 37.5 USD/MWh with a payback period of 11.5 years. Also, the required cost for site optimization (RCO) per kWth of exergy destruction and energy loss for the solar field configuration #1 is found to be 1830.2 USD and 1887.5 USD respectively. These results figure out that there are some possible improvements to be achieved. However, the values for the solar field configuration #2 and #3 are closed to the minimal RCO per kWth. This means that no further improvement can be achieved.

Summary An improved solar parabolic trough collector model has been developed in this study, to overcome the weakness of the previous published studies in predicting accurate performance, at higher operating temperatures. To check the accuracy of the proposed model, both on‐sun and off‐sun tests have been considered. The on‐sun tests are aimed to check the potential of the model for predicting the thermal efficiency while off‐sun tests are for heat losses. The results have indicated that the efficiency uncertainties of the present model are lower than those obtained during the experimental tests of Sandia National Laboratory for all the cases. When compared with previous published models, the proposed model is ranked first, more accurately than those of NERL, Garcia, and Behar. An average uncertainty of less than 0.50% has been obtained while Behar's model show less precision with a deviation of more than 0.55%. The models of Forristall and Garcia‐Valladares have been ranked third and last respectively, with absolute uncertainty of 0.782% and 1.202%. The evaluation of the accuracy of the model in predicting the heat losses have been carried out based on 7 test cases of different ambient conditions. At higher operating temperatures, the present model has shown significant improvements. At 350°C, the model has shown an uncertainty similar to that of experimental tests, ie, 7.3 W/m2. Moreover, it has been ranked first with an average deviation of 3.42 W/m2, more accurate than those developed by Behar, Garcia, and Forristall. If the glass of the solar receiver is broken during operation, the present model might offer some knowledge about their performance. Indeed, the model has also been checked for predicting the thermal performance of PTC with air in the annulus of solar receivers. The RMSE is found to be less than 1.5% for the case of efficiency during on‐sun tests, and values of 2.292% and 1.562% have been obtained for Garcia‐Valladares and Forristall models. Similar finding has been observed for the case of heat losses. Therefore, the proposed model might be an accurate tool for parabolic trough collector performance predictions.

Abstract. The paper analyzes the "secondary" circuit (for thermodynamic conversion) of a Concentrated Solar Power (CSP) plant with thermodynamic cycle, whose mirrors field supplies a thermal power, averaged over a sunny day, of about 100 MW heat. We study the case of parabolic trough solar collector using silicone oil in the "primary" circuit, which limits the peak temperature below 400°C. The "primary" circuit uses thermal storage, allowing a delay between the power generation in rapport with the solar energy capture. We choose a water-steam cycle, type Hirn. For increasing its efficiency, it has regenerative feed water preheating and steam reheating. We compared, energetic and exergetic, two types of cycles, using a numerical model with iterative structure, developed by the authors. The results showed that the simplified design achieves practically the same thermodynamic performances with the advanced one.
