A guided access and charging optimization method for electric vehicles in parking lots

Abstract

The invention discloses a guiding access method suitable for electric vehicles in a parking lot, comprising: S1, establishing the adjacency matrix of the traffic road network; S2, determining the selection and ordering of the electric vehicle parking lot according to the adjacency matrix of the traffic road network; S3, according to the parking lot According to the remaining vacant charging parking spaces in the field and the guidance feasibility constraints, determine the result of electric vehicle guidance access. A method for optimizing charging is disclosed, including: S4. According to the result of guided access of electric vehicles, and on the basis of taking into account backup compensation, optimize the charging and discharging power of a parking lot. The present invention obtains the guided access result of the electric vehicle parking lot by introducing guidance feasibility constraints. After the guidance occurs, the number of corresponding electric vehicles waiting for access at each moment in the parking lot decreases significantly, and the phenomenon of waiting for access in the parking lot is further alleviated. , corresponding to the fact that the actual access time of electric vehicles is significantly higher than before; according to the guided access results, the charging and discharging power of the parking lot is optimized to ensure the daily profit of the parking lot operator.

Description

technical field [0001] The invention relates to a guiding access and charging optimization method suitable for electric vehicles in a parking lot, and belongs to the field of charging energy management of electric vehicles. Background technique [0002] Constrained by the speed of infrastructure construction, the contradiction between electric vehicles and charging infrastructure has become increasingly prominent. After the electric car arrives at the parking lot, if there is no sufficient charging device, it can only be connected to the grid after waiting for other vehicles to leave. A large number of electric vehicles connected in disorder will aggravate the waiting situation in the parking lot, shorten the actual access time of electric vehicles, and then affect the ability of electric vehicles to participate in providing auxiliary backup. Therefore, in order to avoid this phenomenon, it is necessary to formulate a comprehensive guidance strategy and operation mode for t...

AI Technical Summary

Problems solved by technology

There are limitations in the traditional electric vehicle charging guidance method, such as: while establishing the electric vehicle guidance mechanism, it focuses on the interior of a single parking lot, and does not consider the feasibility of guidance between different parking lots

Usually, the goal of maximizing the parking lot operation is pursued, and the proposed access discrimination mechanism is not easily accepted by users.

When studying the participation of electric vehicles in providing backup, the lack of consideration for the limitation of the number of charging facilities affects the accuracy of the model
