Provided is a power grid adjustment method based on a load of a variable frequency air conditioner. The method includes: establishing a mathematical simulation model of a virtual synchronous motor in a variable frequency air conditioner controller; establishing a virtual inertia control segment and a droop control segment of power grid adjustment according to the mathematical simulation model; obtaining a reference value &#x394;&#x3c9; of rotation speed variation of a compressor by the virtual inertia control segment; obtaining a reference value &#x3c9;of rotational angular frequency of the compressor by the droop control segment; and inputting a sum of the reference value &#x3c9;of rotational angular frequency of the compressor and the reference value &#x394;&#x3c9; of rotation speed variation of the compressor into a field-oriented controller (FOC) to control rotation of a motor.
