Digital modeling and simulation method based on intelligent planning of power distribution network

The invention discloses a digital modeling and simulation method based on intelligent planning of a power distribution network, and the method comprises the following steps: S1, considering the power data and time-varying law of electric equipment, and extracting a multi-time-scale load distribution vector through calculation; s2, building an architecture of a geographic element distribution form of the power distribution network, and constructing an objective function of road network information in a transformer substation prediction process; s3, constructing an intelligent planning digital model for the infrastructure according to the road network information; and S4, testing the effectiveness of the intelligent planning digital model in different simulation experiment scenes. The problems that the subjectivity of planning schemes is large and different schemes are difficult to quantify and compare due to the fact that research in the existing power distribution network planning field is still completed mai
