Power distribution network optimization scheduling method based on electric vehicle two-stage rolling strategy

Abstract

The invention discloses a power distribution network optimization scheduling method based on an electric vehicle two-stage rolling strategy. According to the invention, modeling is carried out on thecharging demand of an electric vehicle, a real-time scheduling strategy of the electric vehicle is obtained through a grouping mechanism, the prediction value is updated in a two-stage rolling mannerby utilizing the latest power prediction information on the basis of day-ahead scheduling, the charging strategy of each sub-group of the electric vehicle is formulated, and the real-time scheduling of the electric vehicle is carried out through the charging and discharging priority. According to the two-stage rolling type strategy adjustment real-time charging optimization method, the model solving difficulty can be remarkably reduced and the model solving speed can be improved. The method can be applied to reasonable and feasible scheduling of an actual power grid, enables the scheduling ofthe electric vehicle to truly participate in the actual scheduling of the power grid, achieves the peak load shifting, and improves the permeability of renewable energy in the power grid.

Description

Problems solved by technology

[0003] Although electric vehicles have a positive impact on energy and environmental protection issues, because their driving status and charging demand are affected by many factors such as the user's subjective will, there are great uncertainties in time and space. Charging according to your own electricity consumption habits will increase the peak load of the power grid and add new burdens to the operation of the distribution network
