Impact of electric vehicle charging on power grid

This paper analyzes the prospect and the associated impact on power grid of large-scale applications of electric vehicles, and the countermeasures to reduce such kind of impact. Electric public bus, electric mini-car and electric passenger car have good prospects, so that they will became a great charging load. It also will produce a variety of disadvantage effects to the distribution network under the natural charging mode. These effects can be reduced by rebuild and expansion of the distribution network, governance of technology and orderly utilization. Orderly utilization can improve acceptance ability of power grid greatly without adding new facilities, so it should be a prior method in use.
