Flexible planning method of power distribution system suitable for large-scale application of electric automobile

The invention discloses a flexible planning method of a power distribution system suitable for large-scale application of an electric automobile. The method comprises: based on the minimum sum of investment and operation costs, establishing a power distribution system expansion planning model, and giving a charging load calculation method in a disordered and ordered charging mode; on the basis, considering various uncertain factors such as loads in the system, applying a scene analysis technology, forming a scene by three vectors such as a conventional load predictive quantity, an electric vehicle ownership quantity and a charging mode, and obtaining a solution through an effective optimization solver GUROBI, so that a flexible planning model of the power distribution system is obtained; and finally, explaining the proposed model and strategy by using an example. According to the method, an initial construction scheme with low cost can be provided for investors, the adaptability of thescheme to other possible
