The invention discloses a load characteristic prediction method considering the influence of a distributed power supply and an electric vehicle. The method comprises the steps of firstly collecting load prediction basic data, then respectively predicting an expected output curve of a distributed power supply, an expected charging load curve of an electric vehicle and a typical daily net load curve, then predicting the typical daily load curve considering the influence of the distributed power supply and the electric vehicle, and analyzing load characteristics. According to the design, the influence of the distributed power supply and the electric vehicle on the load characteristics of the main network is comprehensively considered, and the load characteristic prediction problem can be accurately solved under the condition of large-scale development of the distributed power supply and the electric vehicle.
