The application discloses a virtual reactance inverter grid-connected method based on droop control, which is based on the reference voltage generated by single-loop droop control and the dq-axis current, and adds virtual impedance control to generate virtual voltage to correct the reference voltage. The implementation effect of the method is equivalent to the increase of the internal inductance of the power grid, and the effect of weakening the strong grid inertia connected is achieved, so that the stability of the single-loop droop control inverter connected with the strong power grid is strengthened. The application is applied to the grid-structured single-loop droop control inverter, can realize the function of stable interconnection of the single-loop droop control inverter and the strong power grid, and has the characteristics of simple control method, less input devices and the like.
