Electric Vehicles as an Integrated Part of Energy Storage Systems in Renewable Hybrid Energy Supply Systems

摘要

An extensive usage of renewable energy sources implies, because of their local and time dependant stochastically behaviour, a decentralised supply structure. Thereby, the different possibilities of renewable energy converter are to be combined with respect to their complementary character, resulting in so-called hybrid systems. But it would not be possible to build up a more effective, rational, and as far as possible renewable future energy supply system and structure, without a consequent integration of the transport and traffic technology. Most important for this is a complex and interconnected view of these problems as one whole undividable unit. Because of the different stochastically and dynamical behaviour, it seems to be unavoidable for such supply systems to integrate sufficient energy storage capacities. A careful dimensioning of hybrid systems and their interconnections can help to reduce these capacities to an absolute minimum only for security. A special capacity would be necessary to cover the peak power short-time demands, in order to avoid an over dimensioning of the hybrid system converter. In this case electric vehicles could serve as (additional) storage capacities, if they were not used for driving.
