Distribution network planning method and equipment based on distributed power supply configuration uncertainty

The invention discloses a power distribution network planning method and device based on distributed power supply configuration uncertainty. The method comprises the steps of obtaining distributed power supply configuration conditions, performing modeling based on the distributed power supply configuration conditions to obtain an influence model, and analyzing power distribution network operation parameters according to the influence model to generate planning requirements; constructing a first-level planning function and a second-level planning function based on the planning requirements; calculating the first-level planning function and the second-level planning function to obtain a planning result through iterative solution; and correcting the planning result according to a pre-constructed planning result distribution model to obtain an optimal planning result. According to the embodiment of the invention, the method can achieve the precise related planning of the power distribution network under the plann
