Research on impacts of electric vehicle charging station location on voltage stability
摘要
Abstract
In order to research the impact of Electric Vehicle (EV) charging station location on voltage stability of power grid, an analysis method based on electric betweenness is proposed. The variation of system voltage distribution after respectively connecting the high electric betweenness and low electric betweenness nodes into EV charging station is quantitatively analyzed, and then the impacts of electric betweenness on voltage stability are discussed based on voltage stability margin index of PV curve. It finds that node electric betweenness is in direct proportion to its capacity of absorbing new loads, the nodes with higher electric betweenness can bear greater range of voltage variations when the same quantity of load is increased, and the system voltage stability is much better. Simulation results show that EV charging station locating on higher electric betweenness node is helpful for absorbing new charging load, enhancing load level of all level, maintaining system voltage stability, and reducing the risk of voltage collapse.关键词
