The invention discloses a frequency modulation method and system for a fused salt coupling thermal power generating unit, and the method comprises the steps: obtaining a frequency modulation instruction, and determining an optimal decomposition layer number through a trained prediction model based on the frequency modulation instruction; based on the optimal decomposition layer number, the frequency modulation instruction is decomposed through a VMD algorithm to obtain modal quantities and residual components, and the number of the modal quantities is the optimal decomposition layer number; based on the modal quantity and the residual component, a high-frequency power component and a low-frequency power component are obtained, the high-frequency power component is sent to the fused salt as a fused salt frequency modulation power instruction, and the low-frequency power component is sent to the thermal power generating unit as a thermal power generating unit frequency modulation power instruction. Therefore, t
