Parameter Optimization of a Hybrid Solar Concentrating Photovoltaic/Concentrating Solar Power (CPV/CSP) System

Parameter optimization of a hybrid CPV/CSP system is investigated using energy analysis with a steady-state physical model. Two kinds of solar radiation flux density distribution, the Gaussian distribution (GD) and the trapezoidal-shaped distribution (TSD), are employed in the analysis. Three influencing parameters including the average optical concentration ratio, the outlet temperature of R134a from the solar thermal receiver, and the saturation vapor temperature of R134a are taken into consideration. The results show that, increasing the average optical concentration ratio, decreasing the outlet temperature of R134a from the thermal receiver, and selecting appropriate saturation vapor temperature are the effective methods for increasing the power output of the proposed hybrid system.
