The invention discloses a control method for inhibiting the offset of a transient virtual power angle curve of a drop-controlled inverter. A feedforward parameter adding method is adopted for calculating an output current of the inverter and carrying out feedforward control on the output current, so that the voltage tracking performance of the inverter is improved, and the transient stabilization of the inverter is kept. Two feedforward output voltage estimated values are added to two current reference values generated by original voltage outer rings of the inverter, so that neo current reference values are obtained. By adopting the method, the transient tracking performance of the voltage is improved, the transient offset of the virtual power angle curve is effectively inhibited, additional sensors are not needed, and the good transient state and the small interference performance of the system are ensured; in addition, the method can be applied to inverters under dual-loop control such as a virtual synchronous machine, the method can also be further popularized to large interference scenes such as multi-machine passive isolated grids and isolated grid large-load switching, and the transient stabilization of the system is improved.
