Stochastic Modeling of PHEVs Penetration Impact on Distribution Transformers Daily Aging

One of the solution for decreasing pollution in big cities is using of electric vehicles. Old combustion engine vehicles decreased Contamination of the environment. By using Hybrid Electric vehicles environmental pollution will reduce economically. One of these HEVs is plug-in HEV or PHEV. These types of vehicles are using electricity charger to charge their batteries from electricity distribution networks. So they impact on distribution transformer loading. Because many of vehicle owners start to charge their vehicles as arrive to home. In this paper assumed that vehicle owners can charge their vehicles at work and in home. This uncoordinated charging impact on distribution transformers daily aging and daily trip cost of owner vehicles are simulated based on stochastic modeling of PHEVs owner behavior at any day. Results of this topic on IEEE RBTS distribution network are presented.
