The invention discloses a comprehensive benefit evaluation method for orderly charging of electric vehicles in a three-phase power distribution network. The method comprises the following steps: acquiring basic charging parameters of the electric vehicles; establishing a constraint condition of charging of an electric vehicle aggregator, a constraint condition of power flow of a distribution network, a constraint condition of standby supply and constraint conditions of new energy output, outsourcing power and node load of the distribution network; establishing a distribution network operation objective function, and obtaining an optimal operation model of the distribution network; the electric vehicle charging basic parameters are substituted into the distribution network optimal operation model, and an electric vehicle disordered charging operation result and an electric vehicle ordered charging operation result are obtained respectively; and according to the disordered charging operation result of the electric vehicle and the ordered charging operation result of the electric vehicle, the ordered charging comprehensive benefit of the electric vehicle is determined. According to the invention, the accuracy of comprehensive benefit evaluation of ordered charging of the three-phase power distribution network electric vehicle can be improved.
