摘      要：This paper proposes a comprehensive thermodynamic and economic model to predict and compare the performance of concentrated solar power plants with traditional and novel receivers with different configurations involving operating temperatures and *** simulation results reveal that power plants with novel receivers exhibit a superior thermodynamic and economic performance compared with traditional *** annual electricity productions of power plants with novel receivers in Phoenix,Sevilla,and Tuotuohe are 8.5%,10.5%,and 14.4%higher than those with traditional receivers at the outlet temperature of 550℃.The levelized cost of electricity of power plants with double-selectivecoated receivers can be decreased by 6.9%,8.5%,and 11.6%.In Phoenix,the optimal operating temperature of the power plants is improved from 500℃to 560℃by employing a novel ***,the sensitivity analysis of the receiver heat loss,solar absorption,and freeze protection temperature is also conducted to analyze the general rule of influence of the receiver performance on power plants *** absorption has a positive contribution to annual electricity productions,whereas heat loss and freeze protection temperature have a negative effect on electricity *** results indicate that the novel receiver coupled with low melting temperature molten salt is the best configuration for improving the overall performance of the power plants.
