Flexible operation for solar-assisted sCO2 recompression Brayton cycle was analyzed. Two operational modes for dealing with solar transient periods were identified. The role of solar multiple factor on the design operation was examined. Constant power production from various operation regimes was targeted. A significant fuel saving ratio for indirect configuration was found.
