The invention relates to the technical field of power grid frequency modulation, in particular to a frequency modulation method and system for a fused salt coupling thermal power generating unit, and the method comprises the steps: determining a power grid frequency modulation response demand based on a received frequency modulation instruction; decomposing the power grid frequency modulation response demand through a VMD algorithm to obtain a plurality of modal components; sorting all the modal components based on the power spectrum entropy and the permutation entropy value of each modal component to obtain a target sequence, and dividing the target sequence according to a set number of intervals to obtain a permutation and combination total number; calculating evaluation indexes under different permutation combinations for all intervals corresponding to various permutation combinations to obtain a target permutation combination when the evaluation index is maximum; dividing all intervals corresponding to th
