| Abstract:With the continuous increase of new energy vehicle ownership, large-scale access of electric vehicle exerts certain impacts on the safe and stable operation of the urban distribution network, thus research on the accommodation of the distribution network for electric vehicles is badly needed. Based on the performance parameters and driver behavior characteristics of different types of electric vehicles, this study establishes the charging power demand model of electric vehicles, and analyzes the influence of certain scale of accessed electric vehicles on the daily load curve of the distribution network. Four different scenarios including electric vehicle V2G and DG grid-connected generation are set up and the accommodation capacity of the distribution network for electric vehicles is quantitatively analyzed from two aspects of voltage deviation and static voltage stability limit. The accommodation capacity for electric vehicles in four different scenarios is compared with IEEE33 node distribution network as an example. |
