【 摘 要 】

After the large-scale electric vehicles are connected to the distribution network, the load on the distribution network is increased and the power quality of the distribution network is affected. In this paper, in line with various factors related to the demand for charging power, the charging power of electric vehicles is modeled according to the travel rules of electric vehicle users, and the load changes of the original distribution network caused by different sizes of electric vehicles connected to the distribution network are simulated. This paper uses Monte Carlo method to evaluate the reliability of the power grid. Taking the IEEE-RBTS Bus2 power distribution system as an example, the paper analyzes and calculates the reliability index of each load point, and studies the influence of different scale electric vehicles accessing the distribution network on the reliability index of the distribution network.
