An Assessment Method for the Impact of Electric Vehicle Participation in V2G on the Voltage Quality of the Distribution Network

In order to further evaluate the impact of vehicle-to-grid (V2G) on distribution network, this paper studies a method assess influence electric vehicles participating in charge and discharge voltage quality network. First, considering state EV, participation owner other factors, charging discharging model is built. Then, probabilistic power flow calculation based Latin hypercube sampling used obtain probability amplitude load connected finally evaluation index established quantify calculate network V2G process vehicles. Simulation results show that has advantage fast speed while ensuring known accuracy, introduces expected value variance quantification amplitude, more intuitively understands degree before after V2G, can effectively accessing mode low-voltage residential areas industrial commercial areas, provide useful reference for formulation future control strategies planning urban grids.
