Abstract

The invention relates to an ordered charging control method for accessing an electromobile into a residential area in scale. The method comprises the following steps: establishing an electromobile charging load model by comprehensively considering a travel behavior of a private car and a user charging behavior, and optimizing a grid load curve by proposing two charging control methods based on theoptimal parameter valid interval. By optimizing the electromobile charging control method at the residential area, the method is in favor of balancing the load of the grid, thereby enabling the power-supply grid to operate more economic and safe.

Description

technical field [0001] The invention relates to the field of intelligent electricity consumption in residential areas under the condition of large-scale access of electric vehicles, in particular to an orderly charging control method for large-scale access of electric vehicles to residential areas. Background technique [0002] As a new energy vehicle, electric vehicles can effectively alleviate the increasingly prominent contradiction between fuel supply and demand and environmental pollution. Countries all over the world have vigorously promoted and promoted the development of electric vehicles. It is foreseeable that with the expansion of the scale of electric vehicles and the gradual improvement of charging facilities, more and more families will charge electric vehicles in residential areas. However, when a large-scale electric vehicle is connected to the grid as a load, if its charging behavior cannot be controlled correctly and orderly, it will bring great risks to th...
