Abstract

The promotion of electric vehicles (EVs) has eased the shortage of fossil fuels, but also brings challenges to the grid. Load modeling of EV is an important technical reserve to deal with the challenge. From practical application, this paper built the model of charging system consisting of voltage source PWM rectifier, phase-shift full bridge ZVS DC-DC converter and power battery pack and connected the model built to distribution system containing composite load. Furthermore, the paper calculated the critical clearing time of induction motor and used it as an index to evaluate the transient voltage stability under different EV penetration rate. Then the impact of dynamic characteristics of EV charging station on transient voltage stability of distribution network and its influence factors was analyzed. The results provided useful information for the safe and stability of power system with large-scaled EV accessed.
