Electric Vehicle Charging Load Management and the Impact on the Power Grid

With the shortage of oil resources, oil consumption, it would also followed by generation of air pollution and greenhouse gas. As China's oil consumption is enormous, it can be predicted that in the future, oil will restrict China's economic development. In this case, the development of electric vehicles can be seen one of the best solution as an alternative to this fossil fuel vehicles. But electric vehicle charging poses a serious problem for the safe operation of the power system; for instance, it may lead to Grid voltage drops, generate harmonic, etc. This article discusses the relationship between the smart grid and electric vehicle charging load, then introduce the electric vehicles grid solutions.
