Quick charging price correction method for double-layer electric vehicle for distribution network voltage control

Abstract

The invention relates to a double-layer electric vehicle quick charging electric price correction method for voltage control of distribution network, which is characterized in that the method comprises the following steps: 1, utilizing electric vehicle mobility simulation model to predict electric vehicle quick charging demand, namely travel information requiring quick charging; 2, utilizing electric vehicle mobility simulation model to predict electric vehicle quick charging demand. 2, according to the travel information required for quick charging obtained in the step 1 and the quick charging price scheme determined by the upper optimization model, determining the user needing quick charging and selecting the quick charging station, and further determining the charging load of the quickcharging station; 3, construct an upper optimization model; according to the fast charging demand of electric vehicle and the fast charging station load determined by the lower level model, the modeloptimizes the fast charging station price scheme with the objective of minimizing the total voltage amplitude deviation. By optimizing the fast charging price, the invention guides the fast charging load redistribution, so that the total offset of the distribution network is minimized and the income of the fast charging station is ensured to remain unchanged.
