Power distribution network business expansion assessment method, system and device

The invention discloses a power distribution network business expansion assessment method, system and device, and the method comprises the steps: selecting an access point according to user demand information, and determining the maximum allowed installation capacity of the access point; determining an evaluation index of the power distribution network business expansion installation to-be-evaluated scheme, and setting a constraint rule for the evaluation index; and under the condition that a constraint rule of evaluation index setting is satisfied, according to the weight of the evaluation index, a genetic algorithm is adopted to select a plurality of to-be-evaluated schemes of the access point, and a business expansion scheme is generated. According to the method, the genetic algorithm is adopted to optimize and select various power supply schemes, various factors are comprehensively considered, and a reasonable power supply scheme can be quickly formulated for a user under the condition of meeting safe and
