Research and Analysis on V2G Technology and Its Application

Abstract

In recent years, with the increasing popularity of new energy vehicles and the gradual increase in the number of charging piles, V2G technology has gradually emerged. Compared with the traditional grid charging system, which mostly uses natural energy, has unstable charging, and is difficult to interact with the grid, V2G technology uses new energy electric vehicles to interact with the grid, which has a better effect of adjusting the grid balance, peak shaving and filling, adjusting power consumption, and allowing more users to participate in power generation. This article studies the definition and principles of V2G technology, as well as its development history, relevant research and innovation achievements in this field. Secondly, the article expounds on the basic working principle and practical application of V2G, including interaction control systems, grid interaction, and virtual power plants. In order to verify the basic principles of V2G technology, this article constructs and simulates a Simulink circuit to convert the direct current of electric vehicles into alternating current of the grid by step-up inverters, further verifying the basic working principles of V2G.
