The invention discloses a fan energy pre-storage combined frequency modulation method and system based on frequency prediction, computer equipment and a storage medium. When the power grid frequency fluctuates, the change trend of the frequency is predicted through a frequency prediction model constructed based on a CNN algorithm, the deviation value of a frequency prediction curve and a standard frequency modulation frequency curve is calculated through a relative deviation algorithm, and constraint conditions of energy storage action and pre-energy storage combined primary frequency modulation control are set. And judging whether the fan is marked as different states or not according to the condition that the real frequency change meets the constraint condition and the threshold constraint condition of fan state switching, and executing corresponding actions. According to the method, support can be quickly provided for power grid frequency change, the power grid frequency supporting capacity ...
