Double-layer electric vehicle fast charging electricity price correction method for distribution network voltage control

Abstract

The present invention relates to a double-layer electric vehicle rapid charging electricity price correction method for distribution network voltage control, and its technical characteristics are: comprising the following steps: Step 1. Using the electric vehicle mobility simulation model to predict the fast charging demand of the electric vehicle , that is, the travel information that needs fast charging; step 2, according to the travel information that needs fast charging obtained in step 1 and the fast charging price plan determined by the upper optimization model, determine that the user who needs fast charging should choose a fast charging station, and then determine the fast charging The charging load of the station; step 3, constructing the upper layer optimization model; the model is based on the electric vehicle fast charging demand obtained from the electric vehicle simulation model and the fast charging station load determined by the lower model for the corresponding price plan, and the total voltage amplitude deviation is the smallest The goal is to optimize the price plan of fast charging stations. The invention guides the redistribution of the fast charging load by optimizing the fast charging price, so that the total deviation of the distribution network is minimized while ensuring that the income of the fast charging station remains unchanged.
