Abstract：In recent years, the electric vehicle technology has been developing rapidly due to the concerns for the environment and energy. This will bring major impacts on the grid. The effects of electric vehicle on low voltage network are analyzed in this paper with simulations in uncontrolled charging mode, coordinated charging mode and V2G mode. The results show that the electrical peak demand may increase when the charging is without regulation, which will cause the increased capacity demand for substations. If the charging management plans properly and the V2G technology can be fully used, the load curve can be adjusted effectively without increasing substation capacity. In addition, the oversupply of renewables can also be consumed.
