The invention discloses an extra-high-voltage direct current correction method considering sending-end and receiving-end power grids. The method comprises the following steps: establishing an extra-high-voltage direct current correction model objective function considering a new energy consumption space of the sending-end power grid and a peak regulation margin of the receiving-end power grid; establishing constraint conditions of the extra-high-voltage direct current correction model objective function; calculating and determining a corrected extra-high-voltage direct current tie line power curve according to the extra-high-voltage direct current correction model objective function and the constraint conditions; and adjusting the power of an extra-high-voltage direct current tie line according to the corrected extra-high-voltage direct current tie line power curve. The method considers reduction of wind curtailment and light curtailment rates of the sending end, and meanwhile, reducespeak shaving pressure of the receiving-end power grid and ensures stable operation of the receiving-end power grid.
