The invention relates to the technical field of power grid frequency modulation, and particularly provides a novel frequency modulation method and system for a fused salt energy storage coupling thermal power generating unit. Taking three continuous values of the decomposition layer number as one group, and decomposing the hybrid energy storage response demand by using a VMD algorithm through the decomposition layer number group to obtain a corresponding modal component candidate group so as to obtain a target modal component group; correcting the target modal component group to obtain a corrected modal component group, and obtaining a difference evaluation index based on the corrected modal component group and the aliasing degree; updating the decomposition layer array based on a set decomposition layer number range to obtain new difference value evaluation indexes, and obtaining a high-frequency component and a low-frequency component based on the correction mode component group corresponding to the minimum
