V2XPLORE – Potentials of bidirectional commercial vehicles for companies, grid and the energy system

The project V2XPLORE examines the potential use of electric vehicles as mobile storage devices that can be charged bidirectionally (Vehicle-to-X, V2X). This is achieved by analysing various use-cases that give us a better understanding of the interaction between the involved actors on different levels. 

It is the aim of V2XPLORE to better understand the potentials and impact of biderectional charging on different levels and for various actors, by themselves and when interacting, while taking into account different classes of vehicles (cars, lorries, busses). In concrete terms, the actors and sources of income are to be identified, and the proceeds and costs are to be deduced by V2X on a single level as well as in an integrated overall view in order to derive recommendations for the various involved actors. In the process, we address the following questions:

  • On which level - company, grid or market - and for which actors does V2X provide the greatest benefit?
  • How can the relevant actors be supported (financially)?
  • What barriers exist and what are the next steps that are necessary from a sytem point of view?

In the framework of V2Xplore, we examine three central levels, for which we analyse the use of V2X singly and in interaction:

  • User level (households and companies)
  • Distribution network level (various types of distribution networks)
  • System level (the German energy system as a whole)

Each of these levels involves different actors, among them households, vehicle fleet operators, distribution network operators and political decision makers in the regulatory field. Potential returns result from different use-cases like the optimisation of PV-owners' own consumtion, the optimised sourcing of energy via dynamic pricing or the provision of operating reserve, which can benefit different levels.

From a methodical point of view, we use three existing models (ALADIN for the user level, EVaTar for the distribution network level, Enertile for the entire energy system), which we develop further and interconnect within the framework of the project. 

For practical relevance, an accompanying group was established, with which project results are continously discussed. Furthermore, three case studies are caried out with practice partners in the framework of the project in order to address economic and technical questions..
