【Abstract】 In the case of distribution network failure, to relieve the pressure on distribution network operation and reduce the accumulation of electric vehicle due to inability to charge, car accidents and other situations, this paper took the node voltage as the objective function, established the mathematical model of distribution network reconstruction, and improved the harmonic algorithm to solve the distribution network reconstruction problem. The linear weighted sum method was used to minimize the driving distance and charging cost of electric vehicles as objective functions, and the optimal route was found for electric vehicles by determining the best route from the origin to the end poin.This model was a mixed integer constrained programming problem. An experimental example was given to prove that this model could effectively solve the vehicle routing optimization problem in the case of distribution network failure.更多还原
