In this paper, solar power tower stations with different configurations of steam generators are proposed, and a detailed dynamic model of one-dimensional distributed parameters is established and verified. The response characteristics of the two systems under the disturbance of the main controllable variables are calculated, and the results are analyzed and compared. It is concluded that, compared with steam turbines, steam generation systems have significant thermal inertia, and different steam generation system schemes will have a significant impact on the dynamic performance of the system. For a natural circulation-driven system, the energy balance and power output are more sensitive to the hot salt mass flow rate, and mass balance would be adjusted by the feedwater mass flow. For a once-through-driven system, the energy balance is controlled by hot salt mass flow, but the mass balance and power output should be adjusted by the feedwater mass flow.
