Embodiment Construction

[0093] The method for formulating a charging plan based on the time-series response model of an electric vehicle swapping station of the present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings.

[0094]The economic security dispatch of the power grid is an important issue that electric vehicles need to face when connecting to the power grid. The battery pack load margin in the swap station is a good control reference. The charging plan formulation method based on the timing response model of the electric vehicle swapping station of the present invention is to more scientifically and rationally formulate the charging plan of the battery pack in the electric vehicle swapping station from the perspective of the swapping station operator. Firstly, the modeling problem of the active load control capability of the backup battery pack in the station is studied, and based on the number of backup battery packs in the station...

Abstract

The invention provides a charging plan making method based on an electric vehicle battery swap station time sequence response model. The method comprises a step of establishing a backup battery control ability model in a battery swap station for the characteristic of an electric vehicle swap model, establishing a battery group state vector in the battery swap station, grouping battery group controlled states to obtain corresponding state vectors, and determining each state battery group number, a step of obtaining the load margin of the backup battery group in the battery swap station through recursive simulation, comprising calculating the battery swap station load margin of a t time and calculating following time load margin belt according to the actual load of the t time battery group, a step of proposing the making method of a battery swap station service provider charging plan with the combination of the load margin belt of the backup battery group in the battery swap station and the target load determined by a grid operation requirement under the premise of satisfying an electric vehicle swap requirement and a grid operation requirement. On the basis of satisfying the swap requirement, the reasonable regulation and control of the backup battery group charging time and charging quantity is realized, and the economic and efficient operation of the battery swap station is realized.

Description

technical field [0001] The invention relates to a method for formulating a charging plan for an electric vehicle. In particular, it relates to a method for formulating a charging plan based on a time-series response model of an electric vehicle swapping station. Background technique [0002] As issues such as climate change and energy shortage become increasingly prominent, electric vehicles have become the future development direction of the automotive industry. At present, the power supply methods of electric vehicles are mainly divided into charging mode and battery exchange mode, among which the battery exchange mode has the following advantages: short waiting time, high vehicle utilization rate; it can be charged during the low load period of the power grid, and play the role of peak shaving and valley filling; It can assist the local consumption of new energy. At the same time, the battery replacement mode also has the following disadvantages: the initial investment ...
