Several novel concepts related to power generation have been missing in the System Advisor Model (SAM). One such concept, until now, is a hybrid integrated solar combined-cycle (ISCC) system, which has been identified as a potentially cost-effective and lower-risk option for deploying concentrating solar power.
To enable the detailed assessment of this hybridization strategy, National Renewable Energy Laboratory (NREL) scientists have developed a new CSP component to SAM that models a retrofit ISCC system. In this model, power-cycle performance data are connected with SAM’s molten-salt power-tower model.
By adding this hybridization model to SAM, NREL scientists have advanced published models by making it possible to analyze the effect of power-cycle off-design behavior on the solar technology performance.
This expanded capability within SAM will allow a broad community of users to assess the performance and economic viability of new CSP concepts such as solar-field and receiver designs integrated with a brownfield power plant.
Key Research Results
NREL developed a retrofit integrated solar combined-cycle model that connects power-cycle performance data with SAM’s molten-salt power tower model.
This new model determines the effect of power-cycle off-design behavior on the performance of the solar technology.
This development allows SAM users to assess the performance and economic viability of a new CSP deployment option.
