Research on Power Grid Load after Electric Vehicles Connected to Power Grid

Abstract

With the massive popularity of electric vehicles and smart grid applications, the future there will be a large number of electric vehicles connected to the grid, electric vehicle charging will be a huge challenge to the power grid load. This paper analyzes the electric vehicle charging model structure, as well as electric vehicle charging power characteristics of the electric vehicle based V2G technology connected to the grid is analyzed, the study of the composition of the structural model of the charging device will be, and to analyze the access to transmission and distribution network of electric vehicles impact of running on power quality impact. After participating in V2G electric vehicle services and networks, can play a role in the grid load shifting, and can increase the load rate, improve the utilization of electrical equipment, distribution network can play in the bottom of the lower line voltage, peak elevated line voltage, is conducive to the grid security, stability, economic operation.
