Potential and Challenges of V2G Technology in Smart Grid Systems
Under the background of the energy transformation promoted by “double carbon”, the smart grid faces two major problems: renewable energy grid connection fluctuates large, and the load peak and valley difference are large.This paper takes the integration of smart grid and V2G technology as the research core, first sorts out the core concepts, technical characteristics and fusion mechanism of the two, and clarifies the V2G The working principle of the technology and the synergy with the smart grid; then from the three dimensions of power grid load adjustment, distributed energy storage system construction, electric vehicle popularization and energy structure transformation, V2G is analyzed The core development potential of the technology; then analyze the challenges of the incomplete standard system faced by its large-scale landing, imbalance of investment income, and lack of enthusiasm for participating in multiple parties. Studies show that V2G technology can effectively enhance grid resilience and accommodate renewable energy, making it highly valuable for smart grids.This paper constructs a theoretical framework for the deep integration of V2G technology and smart grid, provides practical guidance for the industrial application of V2G technology, and helps the realization of energy transformation and “dual carbon” goals.
