Optimization method of electric vehicle driving path based on network reconstruction

Abstract

The invention discloses an optimization method of an electric vehicle driving path based on network reconstruction and belongs to the technical field of driving path optimization methods. According to the optimization method, a power distribution network reconstruction method is adopted to cope with network attacks, the mathematical model of the method is a double-layer optimization model, the upper layer is a power distribution network reconstruction model, the model takes node voltage of a power distribution network as a target function and screens charging piles according to per unit values of the node voltage, and provides data support for the target function and constraint conditions of a path optimization model; and the lower layer is a path optimization model, and the model takes minimization of the driving distance and the charging cost of the electric vehicle as a target function to find an optimal driving path for the electric vehicle. According to the optimization method of the invention, the reliability and stability of the power distribution network can be improved to a great extent, and the operation pressure of the power distribution network after being attacked can be relieved; and meanwhile, the cost and time of a user are saved, and social and economic losses caused by traffic jam and traffic accidents can be reduced to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of optimization methods for driving routes, and in particular relates to an optimization method for driving routes of electric vehicles based on network reconstruction. Background technique [0002] With the increasingly serious environmental problems, the popularization of electric vehicles and the promotion of our country's national policies, electric vehicles have become very common in our country and become one of the favorite means of transportation for our people. However, incidents of power grid attacks have become more frequent in recent years. [0003] When the distribution network is attacked and a large-scale power outage is caused, electric vehicles cannot be charged in time, resulting in traffic problems such as suspension of electric vehicles, traffic jams, and car accidents, resulting in huge social and economic losses. When the distribution network is attacked, it is very important to optimi...

AI Technical Summary

Problems solved by technology

[0004] Scholars have proposed an analytical framework for the propagation of charging station fault disturbances based on grid-traffic network coupling to describe the impact of grid disturbances on the traffic network, but there are still some difficulties in dealing with the actual distribution network being attacked.

A large number of electric vehicles cannot be charged, which will lead to traffic jams, car accidents and other consequences
