Zusammenfassung:	The embodiment of the invention discloses a virtual synchronous generator control method and control system. The virtual synchronous generator control method at least comprises a frequency regulation control method. The frequency regulation control method comprises the following steps: obtaining a frequency change rate extreme value A generated by a rotor side of the virtual synchronous generator at the switching moment of a to-be-switched load; calculating the maximum virtual rotational inertia Jmax according to the frequency change rate extreme value A, and assigning the maximum virtual rotational inertia Jmax to the rotational inertia J; according to the frequency change rate extreme value A, calculating given mechanical power Pref after high-power load switching; obtaining input mechanical power Pm according to the given mechanical power Pref; obtaining the electromagnetic power Pe of the virtual synchronous generator; and controlling the output frequency of the rotor swing equation of the virtual synchro
