The major increases in oil prices and the rising concerns are key drivers in the growing popularity electric and plug-in hybrid vehicles. Car manufacturers this trend quite well and are developing new models. the 90% of Americans who use their cars to get to work every , the average daily commute distance is 45 km and the average time that cars remain parked is 22 hours. A salient feature these vehicles have in common is the batteries, which provide storage capacity that can be effectively integrated into the . focus on the design of a conceptual framework needs to the electric vehicles into the grid -the so-called V2G . The basic premise we use is to treat the battery vehicles as energy resources that can act both as supply and resources. We assess the deployment of an aggregation of vehicles for the provision of frequency regulation - very fast response times - and energy supply for peak . We also investigate the impacts of the aggregated battery charging load on the low load generation schedules and on requirements. The assessment of these impacts takes consideration the explicit representation of uncertainty and importance of the state of charge as a key variable in the use of batteries for the supply and demand roles. For the framework , we also explore the role of the energy servicesin the V2G integration. The role of V2G in the context of resource integration is discussed. In addition, we the need for the communications/ metering system to the integrated battery vehicles to effectively participate in the operation of the grid and electricity markets.
