The invention provides a flywheel energy storage auxiliary thermal power generating unit frequency modulation method and device, and relates to the technical field of flywheel energy storage auxiliary thermal power generating unit control, and the method comprises the steps: obtaining a target frequency modulation frequency sent by a power grid; determining whether a frequency modulation condition exists based on the target frequency modulation frequency; in response to a frequency modulation condition, decomposing the target frequency modulation frequency into a high frequency and a low frequency; and the thermal power generating unit is adjusted based on the low frequency, and the flywheel energy storage system is adjusted based on the high frequency. The thermal power generating unit and the flywheel energy storage system are controlled and adjusted at the same time through primary frequency modulation, the frequency modulation effect can be improved, meanwhile, the operation advantages of the flywheel ene
