Electric vehicle charging scheduling method based on improved optimization algorithm and terminal

The invention discloses an electric vehicle charging scheduling method based on an improved optimization algorithm and a terminal. The method comprises the steps that a user side terminal system needs to judge whether a user sends a charging request or not according to the state of charge of an electric vehicle battery, if yes, a data acquisition unit obtains the daily charging demand, position information, power distribution network operation conditions, regional charging station information and related data information of a regional traffic network of the electric vehicle, and if not, the user side terminal system sends the charging request; if yes, returning to the previous step for cyclic judgment; the data processing and algorithm calculation unit establishes an optimization model with the minimum power grid load fluctuation and the minimum economic time cost of user charging as targets, inputs the obtained data into the model, and solves a target function by adopting a non-dominated sorting whale optimization algorithm with an elitist strategy; the optimal charging scheme of the electric vehicle is obtained; and the transmission and application unit sends charging scheme suggestions to users, so that ordered charging scheduling of the electric vehicles in the region is realized.
