Analysis of Harmonic Contamination in Electrical Grid due to Electric Vehicle Charging

A vehicle charging station gives electric vitality to reviving electrically controlled vehicles. EV vehicle infiltration will increment bit by bit where 35% is anticipated at 2020 and will arrive at half constantly of 2024. The overall impact on circulation frameworks are brought about by the spread of EV, which will be a generous burden increment and augmentation of the system voltage and harmonic distortion. For charging, EV batteries need DC current so the network AC current will be changed over to DC by using battery charger. The charger will essentially be the rectifier/inverter with controller incorporated for acting as a protection circuit. Electric vehicle charger is a sort of harmonic source load. The harmonic current infuses into the power system during AC-DC changing over procedure, which influences power quality. Harmonics can be suppressed by using filters. In this work, charging station using buck boost and using KY converter was simulated, analyzing the harmonics and ripples in the both charging station. Also analyzing battery characteristics. Also a practical model of charging station was simulated.
