Power Quality Analysis of V2G Charging Station Based on Measured Data

Power quality analysis is of great significance in the study of the interaction between electric vehicles and the power grid. However, most of the existing work does not use real data to analyze the power quality of V2G (Vehicle to Grid) charging station for electric vehicles, and lacks the comparative analysis of different working modes in the station. Therefore, this paper lays a theoretical foundation for the influence of V2G charging pile topology on harmonic characteristics through simulation modeling, and secondly, the MATLAB/Simulink simulation model is established, and the comparison between the simulation and the measured data is given. Then, combined with relevant national standards, the measured power quality indicators are qualitatively and quantitatively evaluated and their advantages and disadvantages are compared. Finally, based on the measured data, different experimental scenarios deeply explore the correlation factors affecting the harmonic portability of V2G charging stations of electric vehicles. This method provides a new idea for harmonic monitoring and governance of V2G charging stations for electric vehicles.
