The Impact of Electric Vehicle Charging Stations on Power Flow Calculation and Grid Loss

Electric vehicle charging stations are high-power load after they are accessed to the grid. Therefore it may result in the redistribution of the grid load, which leads to the change of the power flow and the grid loss increases. The load model of charging stations is established in a typical distribution network model in this paper. The impact on the distribution network power flow after the electric vehicle charging stations accessed to the grid is calculated. And then some measures to reduce the network loss are brought up, which are proved by relational calculation cases.
