This data is the result of an international collaboration funded by SolarPACES within the Task I group. The funded project was entitled "Model Intercomparison and Case Studies Concerning Hybrid CSP-TES/PV-Battery Systems" and was carried out from February 2023 to September 2024. In this study, an international group of researchers conducted an intercomparison of modeling hybrid CSP-TES-PV-battery systems through the execution of case studies. This dataset includes the financial and performance assumptions used within the case studies for CSP-TES-PV-battery system modeling. The dataset can be used to verify newly developed hybrid CSP-TES-PV-battery system models against the case studies conducted within this project. The group conducted four cases studies for comparison including: i) fixed system design, ii) variable load design optimization, iii) flat load design optimization, and iv) fixed system design at varying hybrid capacity factor. All cases studies assume the hybrid CSP-PV plant is located near the Plataforma Solar de Almeria in Almeria, Andalucia, Spain. The dataset includes model outputs for each of these cases studied for the four hybrid CSP-TES-PV-battery system models executed (i.e., MoSES, HOPP, AESOPT, and YACOP). The funded institutes were DLR (Germany), Politecnico di Milano (Italy), KTH Royal Institute of Technology (Sweden), and National Renewable Energy Laboratory (United States of America). The National Renewable Energy Laboratory partnered with Colorado School of Mines to complete this work. More context about the project and specific details about the CSP hybrid system model approaches and case study specifics can found within the final report (which will be linked upon publication).
