The invention discloses a source network coordination peak shaving method giving consideration to DC outwards-transmitted power regulating characteristics, and belongs to the technical field of grid new energy peak shaving. The method comprises the steps: determining an equivalent load change curve of a system according to the current wind power output and load prediction value of the system; establishing a peak shaving model in different peak shaving modes; formulating an adjustment plan of the conventional energy output and the DC outwards-transmitted power under different peak shaving modes; correcting a daily operation plan of the system, and obtaining a system peak shaving operation plan. The method provided by the invention can fully explore the peak shaving potential of the system,achieves the planning of the outwards-transmitted power of the system and the conventional energy output, and provides an idea for the solving of a wind power consumption constraint problem.
