The invention discloses an energy storage converter from-zero voltage raising control method and device for the black start of a power grid. A double-closed-loop structure consisting of a voltage control outer loop and a current control inner loop is adopted. The outer voltage loop controls the AC side voltage of the converter, and gives d-axis and q-axis current control reference values. The inner current loop completes the fast tracking control of the current according to the current reference values given by the outer voltage loop. The output voltage amplitude of the converter is changed bysetting the voltage reference value of voltage outer-loop voltage, and a voltage reference value curve is input to gradually increase the voltage from zero to a target value in the black start process of the power grid. The energy storage converter from-zero voltage raising control method provided by the invention is used in the black-start of the power grid to raise the voltage of the target power grid from zero, reduce the impulse current in the black-start process of the power grid and improve the success rate of black-start of the power grid.
