Probabilistic and Fuzzy Modeling of Charging and Discharging of Electric Vehicles in Presence of Uncertainties Applied to Unit Commitment Problem

Advent of electric vehicles in power systems has a variety of effects. The most important effect of electric vehicles in
the power system, is related to increase of demand due to charging process (G2V) and also power injection to grid V2G In this paper unit commitment problem has been solved considering electric vehicles. Since charging and discharging of electric vehicles depends on factors such as electricity price, fuel price, the rate of charging and discharging as well as the overall behavior of car owners, to cover these uncertainties, both probabilistic modeling and fuzzy sets theory are used
