Embodiment Construction

[0040] The invention provides a method for controlling the orderly charging and swapping of an electric vehicle swapping station. Such as figure 1 Specifically, the following steps are shown:

[0041] 1. Discretize the state of charge of the battery according to the increment of the state of charge of the replaced battery within the unit charging time step: the characteristics of the state of charge of the discretized battery are: set the state of charge of the battery to be 1 when the battery is fully charged, and the state of charge of the empty battery to be 1. The state of charge is 0, if the charge increment caused by charging within the unit scheduling time step (such as 1h) is ΔSOC, then the range of charge amount represented by the kth level is [(k-1)ΔSOC, kΔSOC), divided into for M grades;

[0042] 2. Obtain the demand information of electric vehicles entering the station, and control the battery replacement of electric vehicles in the station and the charging of ba...

Abstract

The invention relates to an electric vehicle battery swap station orderly charging control method. The electric vehicle battery swap station orderly charging control method comprises steps that a battery charged state level is discretized; an electric vehicle battery swap requirement is acquired; the orderly charging model of the battery swap station taking valley filling as a target is built, and the fitness function of the orderly charging control is determined by taking a deviation square sum of a load as an index; the optimal solution of the orderly charging control of the battery swap station is solved by adopting an improved cuckoo search algorithm according to the determined fitness function, and a battery charging schedule is determine for the battery swap station according to the solved optimal solution. By adopting the orderly charging and battery swap control method capable of facilitating operation of a power swap station manager, the number of the electric vehicles participating in battery swap service in each time period and the number of the swapped batteries participating in charging behaviors in each time period are acquired, and the orderly charging and battery swap scheduling of the battery swap station are realized, and therefore the daily operation of the power swap station is satisfied, and a function of filling a valley of a regional power grid is realized.

Description

technical field [0001] The invention relates to an electric vehicle technology, in particular to an orderly charging control method of an electric vehicle replacement station based on an improved cuckoo algorithm. Background technique [0002] As a key technology for energy saving and emission reduction, electric vehicles are one of the most promising ways to solve the energy crisis in the future. With the continuous improvement of electric vehicle driving performance and its potential for cost savings, the user base of electric vehicles is constantly expanding. At present, there are two forms of electric vehicle power supply: vehicle charging and battery replacement. Vehicle charging can be further divided into plug-in charging (including fast charging and slow charging) and wireless charging. In plug-in charging mode, on the one hand, it takes too long for car owners to replenish energy, generally 4-5 hours (fast charging also takes more than 30 minutes), and the conveni...
