Orderly charging scheduling system and method for electric vehicles based on cloud computing

Abstract

The invention relates to an orderly charging scheduling system and method for electric vehicles based on cloud computing, and the method comprises the steps: calculating the task priority of each to-be-charged electric vehicle in each time slice, meeting the requirements that charging is completed in a charging duration set by a user, setting a multi-stage queue according to the priority, enablingthe queue with the high priority to be charged preferentially, sorting the to-be-charged electric vehicles in the queue according to priorities, randomly determining a sequence for the to-be-chargedelectric vehicles with the same priorities, when the idle charging position exists and the priority of each to-be-charged electric vehicle of the user meets the requirement, generating a guide for theuser to arrive at the target position, and guiding the user to arrive at the target position for charging and settlement. The cloud computing platform is used for processing big data, an optimal charging scheme is rapidly and accurately provided for a power grid, a charging station and a user, on the premise that user requirements are guaranteed, the operation safety and benefits of the power grid are improved, and unified dispatching control over charging of the electric vehicles in the regional power grid is achieved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a cloud computing-based orderly charging scheduling system and method for electric vehicles. Background technique [0002] As a new generation of transportation, electric vehicles have attracted extensive attention from governments of various countries due to their advantages of energy saving and environmental protection. Countries around the world have introduced policies to put the development of electric vehicles in an important strategic position. my country is also vigorously developing the electric vehicle industry and has issued a series of development policies. The access of large-scale electric vehicles will pose new challenges to grid load, power quality, grid security and economic operation. One of the challenges is that the concentrated charging of large-scale electric vehicles at the same time will bring a new round of load growth, especially the charging ...

AI Technical Summary

Problems solved by technology

[0006] For the existing technical solutions for the orderly charging of electric vehicles mentioned above, the general solution can solve 1-2 charging focus points respectively, and the focus points include minimizing energy loss, maximizing charging station operating income, maximizing user income, and minimizing user charging waiting time Minimization of charging scheduling deviation, minimization of resource waste, fairness of user charging, etc., most orderly charging solutions cannot meet the above-mentioned charging emphasis needs in many aspects
