The invention relates to a method of determining a DC power control quantity in multi-DC coordination control. The method comprises steps: (1) a DC system DCi participating multi-DC coordination control in the power grid and an AC bus in need of voltage control are determined, and i is between 1 and n; (2) equivalent impedance Zeqi between each DC system DCi and the AC bus is calculated; (3) a power control coefficient Ki of each DC system DCi participating in multi-DC coordination control is calculated; (4) if block fault happens to the DC system DCi, a power elevating quantity delta Pj of the DC system DCj is calculated, j is between 1 and n, j is not equal to i, and according to the maximal operation power of each branch system, the actual power elevating quantity of the branch system DCj is determined. According to the method provided by the invention, through calculating the equivalent impedance between the DC system and the AC bus, the influence degree of different DC system power transfer on specific AC bus voltage is evaluated, the power control quantity which needs to be adopted by each DC system in multi-DC coordination control is determined according to the result, and influences on power grid operation by DC fault power transfer are reduced maximally.
