Embodiment

[0075] Such as figure 1 As shown, the present invention relates to a dual-scale charging guidance method for electric vehicles that takes into account user satisfaction, and the method includes the following steps:

[0076] Step 1. Obtain the electricity load curve of electric vehicles in a certain area from the current to the next 24 hours, and the state of charge information, charging station information, and electricity price information when there is a charging demand;

[0077] Step 2. According to the requirements of electric vehicle users on the time to start charging, divide the electric vehicles into cluster A and cluster B. Cluster A is the immediate charging cluster, and cluster B is the delayed charging cluster. The electric vehicles in cluster A need to upload The start time range for allowing access to charging;

[0078] Step 3: Establish a time-level integrated optimal charging guidance model for electric vehicles based on grid and user charging cost factors, ca...

Abstract

The invention relates to a dual-scale charging guidance method and system for electric vehicles taking into account user satisfaction. The method divides electric vehicles into immediate charging clusters and delayed charging clusters according to the user's requirements for charging periods, and establishes charging clusters at different scales. Satisfaction function; at the time scale layer, consider grid factors and user charging cost factors to establish a model, and adjust the load curve by guiding the start charging time of electric vehicles; at the spatial scale layer, consider charging station factors and user travel cost factors to establish a model, Plan the selection of charging stations for each vehicle to improve the operating efficiency of charging stations; guide the charging behavior of electric vehicle users on time and space scales according to the obtained optimal solution. Compared with the prior art, the present invention realizes the function of optimizing load curve, traffic condition, and utilization balance of charging station equipment while ensuring user satisfaction.

Description

technical field [0001] The present invention relates to the technical field of electric vehicles, in particular to a method and system for guiding electric vehicles with a space-time dual-scale charging in consideration of user satisfaction. Background technique [0002] With its advantages of zero emission, high energy efficiency, and low noise, electric vehicles have become one of the effective means to solve the problem of energy conservation and emission reduction in various countries. Its large-scale application is an inevitable trend of future social development. The charging behavior of electric vehicles connected to the grid has uncertainty in space and time. A large number of electric vehicles connected to the grid for disorderly charging will inevitably bring a new round of load growth to the grid, reduce power quality, and increase grid operation control Difficulty will also reduce the operational efficiency of the transportation network and increase the maintenan...
