Direct-current micro-grid current sharing control method with inertia support and related equipment

The invention belongs to the technical field of direct-current micro-grid control, and particularly relates to a direct-current micro-grid current-sharing control method with inertia support and related equipment, and the method comprises the steps: obtaining a target high-frequency signal of a converter based on the output voltage and output current of the converter, and determining the line impedance according to the target high-frequency signal; constructing a nonlinear droop control following function according to the line impedance; and carrying out following on the dynamic change of the output current of the converter through the nonlinear droop control following function, introducing a virtual direct current motor in the control process, and carrying out current-sharing control on each converter according to the following state of the dynamic change of the output current and an equivalent model of the virtual direct current motor. By combining line impedance and additionally arranging VDCM control, ine
