【 摘 要 】

With the increasing concern over the environmental and energy problems, electric vehicles (EVs) develop rapidly. This paper proposes a deterministic modeling methodology of electric vehicle loads. The modelling of one single EV load is conducted from the dc and the ac side separately, in which the time-varying and voltage dependent load characteristics are considered. The daily loads of aggregate EVs are modelled based on the electricity tariff structure and the initial state of charge distribution. Four types of private EVs are taken as the example to confirm the effectiveness of the proposed methodology. The impact of EV loads on power system voltage stability is analysed. The model developed by the proposed methodology provides accurate EV load characteristics with proper model complexity and it is suitable for long-term large scale power system numerical simulation.
