The invention discloses an orderly charging control method for an electric vehicle based on a hierarchical architecture. The method comprises the following steps: establishing a probability model influencing charging load factors of the electric vehicle by utilizing a Monte Carlo method; calculating the total load of the electric vehicle under ordered charging according to the probability model; establishing an ordered charging control model based on a hierarchical architecture, wherein the ordered charging control model comprises an upper-layer charging control center and a lower-layer transformer area charging station which are connected, and the upper-layer charging control center optimizes the charging process of an electric vehicle by using a particle swarm algorithm according to thetotal load to obtain a power guidance curve; solving an optimal charging time period by the lower-layer transformer area charging station by utilizing a particle swarm algorithm according to the powerguidance curve, and calculating an ordered charging load demand according to the optimal charging time period; and calculating and outputting an ordered charging load curve according to the ordered charging load demand and the basic load. The peak period of the charging load of the electric vehicle can be moved backwards, and the impact of the charging load of the electric vehicle on a power gridis reduced.
