Integration of Electric Vehicles in the Electric Power System [PDF]
Proceedings of the IEEE, 2011 This paper presents a conceptual framework to successfully integrate electric vehicles into electric power systems. The proposed framework covers two different domains: the grid technical operation and the electricity markets environment. All the players involved in both these processes, as well as their activities, are described in detail ...
