Abstract One objective for the 3rd Generation of Concentrating Solar Power technologies is to improve the efficiency of Central Tower, which is among the most promising solar concentration technologies. Central Tower Power Generation Plants are made up of hundreds of heliostats that redirect solar radiation to a target. The precision of the solar tracking is …
Abstract A new optimization method was proposed to design high-performance deformable petal heliostat fields for concentrated solar power. The petal field was divided into individual sectors, each separately designed to balance pattern orderliness and flexibility. A suitable high-dimensional optimization algorithm was identified from 129 different algorithms using multi-algorithm filtering. To examine the proposed method, four …
Abstract Falling particle receiver (FPR) systems are a rapidly developing technology for concentrating solar power applications. Solid particles are used as both the heat transfer fluid and system thermal energy storage media. Through the direct irradiation of the solid particles, flux and temperature limitations of tube-bundle receivers can be overcome, leading to higher operating temperatures …

Abstract: Volume-averaging method constitutes an efficacious approach for analyzing and optimizing the overall efficiency of the porous receivers. However, the accuracy in the prediction of heat transfer process is significantly contingent upon the precise assessment of empirical parameters. The comprehensive parametric study of empirical parameters and solar radiation uniformity is conducted by applying volume-averaging method …
Heliostats in the solar field concentrate sunlight up to the receiver atop the tower in Tower CSP, to heat molten salts. All twenty-four Tower CSP plants currently operating or under construction in China’s 1 GW renewable energy parks utilize molten salts to transfer the solar heat. Nearly all the Tower-type Concentrated Solar Power (CSP) plants …
