Research on the Grid Frequency Regulation Method of V2G System Considering Energy Storage Status and Grid Frequency Deviation

With the rapid development of electric vehicle (EV) and grid interaction technology, the application of Vehicle-to-Grid (V2G) systems in frequency regulation and energy storage management has become increasingly important. This paper studies a grid frequency regulation method for V2G systems that takes into account the energy storage status and grid frequency deviation. By constructing a V2G system model, the influence of energy storage status on grid frequency regulation is analyzed, and a regulation strategy based on genetic algorithm and particle swarm optimization is designed to achieve collaborative optimization of energy storage status and frequency deviation. The proposed regulation strategy is verified through simulation, and the results show that this method can effectively improve the stability of grid frequency while optimizing the utilization efficiency of energy storage devices. This research provides a theoretical foundation and practical guidance for the broader application of V2G systems.
