The invention discloses a high-speed and low-speed frequency modulation resource coordination control method considering energy storage system SOC. The control method comprises the steps of establishing a main control region in an AGC system; establishing a generator set and an energy storage system control model in the main control region, and dividing a high-speed frequency modulation group anda low-speed frequency modulation group; obtaining real-time measurement data from an SCADA system; calculating control deviation of an original region; calculating a high-speed frequency modulation resource energy storage system control instruction according to the original ACE and by considering the energy storage system SOC and the maximum allowable charging/discharging power; performing correction and filtering processing on an ACE control signal in the low-speed frequency modulation group, and calculating the regulation requirement of the low-speed frequency modulation group; generating control instructions of res
