In the future it is expected that vehicles with electric drive will replace those with internal combustion engine. The integration of electric vehicles into the electric power grid will cause effects whenever a large number of BEV (Battery-Powered Electric Vehicle) occurs or high charge values are used. On the one hand, there are local aspects to consider (component utilization, voltage stability, etc.), which are not addressed in this work. On the other hand and central to this work, are global, to control area related aspects (such as load balancing, frequency control) and the context in the multi area electric power systems. Vehicle to Grid (V2G), the power flow from the vehicle to the grid, represents one of the most comprehensive forms of load control.
Despite the limited availability to the electric grid and retention of free battery capacity for mobility, with a high number of participating vehicles, the V2G-power of several decentralized vehicle batteries is an interesting vision. To investigate the question about the V2G-power-potential, which, among others, depends on the number of BEV on the market, a model for its determination was created, using the MATLAB software. With this model, also the number of required BEV on the market can be calculated, so that a predefined V2G-power can be provided for a certain time. The calculation is based on data from a survey of the Lower Austrian mobility behavior from the year 2008.
