Orderly charging control method and system for electric vehicles

Abstract

The invention discloses an orderly charging control method for electric vehicles. The method comprises the following steps: according to a preset multi-objective optimization model and an orderly charging control information base, calculating the charging starting time of the electric vehicles and the number of the electric vehicles allowed to be accessed; sending the charging starting time of theelectric vehicles and the number of the electric vehicles allowed to be accessed to a user; in response to the received feedback that the user allows charging, according to the number of accessed electric vehicles selected by the user, calculating the load capacity caused by charging of the electric vehicles, and superposing the load capacity on the daily basic load curve of the power grid; and in response to the power grid daily basic load curve with the superposed load capacity and the cost of charging the electric vehicle by the user meeting the multi-objective optimization condition, performing charging. The invention further discloses a corresponding system. Orderly charging control of the electric vehiclse is realized, and a reference is provided for the subsequent orderly chargingfield of the electric vehicles.

Description

technical field [0001] The invention relates to a method and system for controlling orderly charging of an electric vehicle, belonging to the field of electric vehicles. Background technique [0002] With the depletion of oil resources and the aggravation of air pollution, our country conforms to the concept of green travel and has introduced many preferential policies for electric vehicles to vigorously promote the development of electric vehicles. Under such an environmental and policy basis, the retention of electric vehicles The volume keeps increasing. At the same time, the rapid increase in the number of electric vehicles has also brought certain problems to the modern power system. Here comes the great challenge. [0003] Relevant studies have shown that large-scale disorderly charging of electric vehicles will further increase the peak-to-valley difference of the power grid, and a large amount of charging load will lead to an increase in the voltage drop of the gri...

Problems solved by technology

[0003] Relevant studies have shown that large-scale disorderly charging of electric vehicles will further increase the peak-to-valley difference of the power grid, and a large amount of charging load will lead to an increase in the voltage drop of the grid nodes, and the voltage drop will lead to an increase in power loss and a decrease in the operating efficiency of the power grid.
