Embodiment Construction

[0019] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0020] Orderly charging belongs to the category of smart grid technology. It is necessary to establish an information connection between electric vehicles and the grid to form an energy management system for electric vehicles in the grid. figure 1 It is a structural schematic diagram of an embodiment of the orderly charging control system for electric vehicles of the present invention. In this embodiment, the orderly charging control system for electric vehicles includes a grid management center and station-level management equipment, and the station-level management equipment manages charging facilities.

[0021] From the perspective of logical structure, the orderly charging control system of electric vehicles can be divided into three layers, in which the grid management center belongs to the grid management layer 1...

Abstract

The invention relates to an electric vehicle orderly charging control method. The method comprises the following steps of accounting and calculating the charging load predicting results at the next time frame as per the history data or the charging demand of the conventional electric vehicle by station level management equipment and uploading the charging load predicting results to an electric fence administration center, calculating the available capacity of an electric fence as per the predicting results at the present time frame and the real-time operation state and sending electric fence available capacity command to the station level management equipment by the electric fence administration center, comparing the charging power demand of the present time frame by the station level management equipment and coordinating the charging demand of the electric vehicle if the charging demand of the electric vehicle is smaller than the charging power demand of the present time frame. The invention further relates to an electric vehicle orderly charging control system. The allowance power of a recharge replacement station is restricted reasonably by the electric fence administration center as per the charging load predicting results submitted by the station level management equipment and the operating condition of the electric fence, thereby avoiding the impact to the electric fence caused by power requirements of the recharge replacement station and coordinating the energy source requirements of the electric fence load and the electric vehicle better.

Description

technical field [0001] The invention relates to the field of energy management, in particular to a method and system for orderly charging control of electric vehicles. Background technique [0002] The power and energy requirements of electric vehicles are jointly determined by multiple factors such as the market size of electric vehicles, driving characteristics, charging behavior of users, capacity and performance of power batteries, charging facility mode and layout, and will show certain changes in time and space. of randomness. The time and geographical distribution of electric vehicle charging demand determine the scale of electric vehicles that the grid can bear. According to people's travel habits, the charging of electric vehicles will be relatively concentrated in time and region. If not guided, the charging load of electric vehicles may increase the maximum load of the power grid, increase the peak-to-valley difference rate, and reduce the safety and economy of ...
