A tool of Vehicle-to-Grid (V2G) concept for voltage plan control of residential electric grid areas with Plug-in Hybrid Electric Vehicles (PHEVs)

Plug-in Hybrid Electric Vehicles (PHEVs) will strongly penetrate in the car fleet. Because of their capacity of energy storage and their connection point that will be uniform on the low voltage residential electric grid in the case of home-charged, PHEVs are very suitable to provide services to the system (or Vehicle-to-Grid application) and thus support electric grids especially for voltage plan control. Thus, this paper proposes a mathematical relationship that defines the ability to control the average voltage plan of a low voltage residential electric grid in function of charge power of all PHEVs connected to the electric grid.
