The invention provides a real-time adjusting method for a direct-current power with wind-power power fluctuation. According to the method, wind-power emergency positive and negative rotation reserve sets of direct-current sending and receiving terminal grids are appointed and are used for dealing with sharp changes of the wind-power power; and the wind-power power fluctuation of the direct-current sending terminal grid is adjusted automatically by AGC sets of the direct-current sending and receiving terminal grids based on automatic adjustment of the direct-current power. Factors including adjusting capability of the direct-current sending and receiving terminal grids, the direct-current power conveying capability, the direct-current power tap switch adjusting capability, and different adjusting strategies are taken into consideration. With the method having high practical feasibility, defects existing in the direct-current power arrangement method in the existing wind-power delivery system can be overcome effectively; the direct-current power can be adjusted flexibly; the adjusting capability and the complementary adjusting characteristic of the direct-current sending and receiving terminal grids can be realized fully; and the e wind-power absorption capacity can be improved effectively.
