The Impact of Electric Vehicles on the Distribution Grid
Distribution grid will be greatly inf luenced when large scale electric vehicles are simultaneously charged or discharged.Firstly,the assumptions related to the charging and discharging power of EVs are discussed,and the probability of daily driving distance is exam ined.Secondly,the probability models of charging tim e,duration and power are studied,and the probability models of discharging time,duration and power are built according to the driving pattern of X city in China and the national household travel survey of Anerica in 2001.Then,the probability equation of single electric vehicles hourly charging and discharging power is derived.After that,the mathematical expectation of above probability e quation is solved by Monte Carlo method.Finally,the impact of large scale charging and discharging electric vehicles on the daily load of X city is analyzed.The results provide the theoretical founda tion for the application of large scale electric vehicles in X city.
