The invention discloses an enhanced droop control method capable of improving the transient stability of an inverter. A method of introducing a non-directional axis voltage component intro droop control as the feedback quantity is adopted; the virtual power-angle characteristic of the inverter is changed; the inverter reaches balance in a current saturation transient process; voltage orientation can also be achieved when the current is saturated, so that the transient stability of the inverter is ensured; and the inverter is prevented from entering a current source mode to lose the stability. The method prevents the inverter from entering a current source instability mode; the method does not change the power sharing characteristic of droop control; and the control method can be applied to other inverters, such as a virtual synchronous machine, employing double-loop control, can also be further popularized and applied to large disturbance scenes of a multi-machine passive isolated network, high-load switching of the isolated network and the like, and improves the transient stability of a system.
