Intelligent community electric automobile ordered charging system and method

Abstract

The invention discloses an intelligent community electric automobile ordered charging system and method, comprising: performing distributed data acquisition on a plurality of charging pile terminals; generating load prediction data based on historic data generated by collected data through a load prediction algorithm; comparing generated load prediction data with real load data to form a contrast chart between the load prediction data and the real load data; performing layered scheduling with peak load shifting as a target, and setting the optimal object of a model, wherein during optimal computation, the objective function of the model levels a load curve in order to make the electricity purchasing cost of a charging station lowest; and after obtaining the charging power of a single charging station in each period, issuing an instruction to the charging station, the charging station receiving the instruction of an upper level to guide community ordered charging. The intelligent community electric automobile ordered charging system and method guarantee area electricity safety and stability, and are of important strategic significance in electric power system stability and safety, and economic operation.

Description

technical field [0001] The invention relates to an orderly charging management system and method for electric vehicles in an intelligent park. Background technique [0002] Carry out research on key technologies for orderly charging of electric vehicles in the region, and charging piles that support centralized coordinated control and harmonic detection. It is necessary to improve the construction of electric vehicle energy service infrastructure, improve the management level of electric vehicle charging and discharging operation in smart parks, and build a unified and strong intelligent It plays an important role in promoting the power grid, promoting the development of the electric vehicle industry, energy saving and emission reduction. [0003] As the basic energy facilities for the construction of smart parks, the research on the orderly charging of electric vehicles and the support of charging piles for the coordinated control of orderly charging has not yet been standa...

AI Technical Summary

Problems solved by technology

[0004] Due to its huge advantages in energy saving and emission reduction, electric vehicles have attracted more and more attention, and will gradually enter people's daily life. No matter what charging method is used for huge electric vehicles, the impact on the power grid will be considerable. The influence of harmonics generated by DC conversion on power quality, and the peak-on-peak load of the grid caused by charging during peak hours, etc., if they are allowed to charge disorderly, it will have an adverse impact on the stability and safe operation of the grid
