Abstract

Distribution grid will be impacted to some extent when large scale electric vehicles (EV) are discharging simultaneously. Firstly, the factors related to the discharging power of EVs are discussed. Secondly, the probability density statistic models of discharging time and discharging duration are built according to the traffic pattern of X city in China and the national household travel survey of America in 2001. Thirdly, the probability equation of single EV´s discharging power at each hour in one day is derived. After that, the mathematical expectation of above probability equation is solved by Monte Carlo simulation method. Finally, the impacts of large scale discharging EVs on the daily load of X city are analyzed. The results provide the theoretical foundation for the application of large scale EVs in X city.
