A control method and system for intelligent orderly charging of electric vehicles

Abstract

The invention provides a control method and system of intelligent orderly charging of electric automobiles. The method includes the steps that the number of the electric automobiles in a region is acquired, and daily charging requirements of the electric automobiles every day in the region are calculated according to the number of the electric automobiles; short-term predicted loads and peak and valley electric charges of a power grid in the region are acquired, and corresponding valley price time periods are formulated according to the daily charging requirements, the short-term predicted loads and the peak and valley electric charges; automobile information, battery information and historical charging information of the electric automobiles are acquired through charging piles in the region, and pre-charging requirements of the electric automobiles are determined according to the vehicle information, the battery information and the historical charging information; charging guiding information of the electric automobiles is determined according to the pre-charging requirements and the valley price time periods, and the to-be-charged electric automobiles are charged in order according to the charging guiding information. Peak eliminating and valley filling are achieved for the regional power grid, the charging cost is reduced, and economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of power grid management, in particular to a control method and system for intelligent and orderly charging of electric vehicles. Background technique [0002] Electric vehicles replace oil with electricity, which is an important means to solve energy and environmental problems. In order for large-scale electric vehicles to be better connected to the power grid, two problems need to be solved: first, scientific and reasonable layout planning of electric vehicle charging stations; second, orderly charging control of electric vehicles to eliminate or reduce The impact of large-scale access to the grid on the power system. [0003] The rapid development of electric vehicle battery and drive technology and smart grid provides a strong impetus for the rapid development and popularization of electric vehicles in the future. Since the function of the charging pile is similar to that of a fuel dispenser, its speci...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a control method and system for intelligent and orderly charging of electric vehicles, which solves the problem of lack of information interaction between existing electric vehicles and the grid charging control center, which easily causes grid load fluctuations due to random charging and increases grid energy loss. It can enable the regional power grid to realize peak shaving and valley filling, reduce the cost of charging, and improve economic benefits
