The proposed quantile mapping method is fit on reanalysis data to first bias correct for regional climate models (RCMs) and is tested on RCMs forced by general circulation models (GCMs) to understand existing biases directly from GCMs. Additionally, we adapt a functional analysis of variance methodology that analyzes sources of remaining biases after implementing the proposed quantile mapping method and consider biases by climate region. The proposed method is able to correct for biases due to seasonality on a monthly time scale as well as produce physically plausible values in the corrected data when compared to observed GHI. Analysis shows that biases from GCMs are generally not geographically specific and that RCMs may contribute strong biases to GHI that need to be corrected for.

A novel FPV system with three-point mooring is proposed in this study, and the stability and mooring strength of the novel FPV system is discussed through the numerical simulation and model tests. An anisotropic ice numerical model is developed to simulate the coupled interaction between ice and the FPV structure based on finite element method-cohesive element method (FEM-CEM), and the accuracy of the ice-FPV structure coupled interaction model is verified based on a series of dynamic ice force model tests. Based on the established coupled interaction model, the dynamic ice force variation law of the proposed novel FPV are investigated under different ice velocities and thicknesses, and dynamic behaviors for mooring lines tension forces are quantitatively studied under sea ice in time domain. Meanwhile, structural damage analysis is carried out by comparing stress and strain. It is found that the component connection position on front sides of the FPV structure are areas where the damage occurs first; Afterwards, cracks are generated in connection positions on the rear side, resulting in complete fracture failure. In addition, different mooring tension states are considered to analyze the effects of ice force and mooring tension.

A key factor in ensuring the safe and efficient operation of CSP plants is the distribution of concentrated flux density on the receiver. However, the non-ideal flux density generated by individual heliostats can undermine the safety and efficiency of the power plant. The flux density from each heliostat is influenced by its precise surface, which includes factors such as canting and mirror errors. Accurately measuring these surfaces for a large number of heliostats in operation is a formidable challenge. Consequently, control systems often rely on the assumption of ideal surface conditions, which compromises both safety and operational efficiency. In this study, we introduce inverse Deep Learning Raytracing (<em>iDLR</em>), an innovative method designed to predict heliostat surfaces based solely on target images obtained during heliostat calibration. Our simulation-based investigation reveals that the flux density distribution of a single heliostat contains sufficient information to enable deep learning models to accurately predict the underlying surface with deflectometry-like precision in most cases, achieving a median Mean Absolute Error of approximately 0.14<!--> <!-->mm). When integrating the iDLR surface predictions into a ray-tracing environment to compute flux densities, our method achieves an accuracy of 92%, surpassing the performance of the ideal heliostat assumption by 25%. Additionally, we assess the limitations of this method, particularly in relation to surface prediction accuracy and resultant flux density predictions. Furthermore, we present an innovative and efficient heliostat surface model based on NURBS. This approach achieves a highly compact representation, requiring only 256 parameters to define the surface—a reduction of 99.97% in the amount of parameter and a 99.91% in memory usage. This efficient model enables resource-effective deep learning for heliostat surface predictions, positioning it as a promising state-of-the-art solution for heliostat surface parameterization.
