An electric-vehicle-based supplementary power delivery system

Renewables provide clean and economical energy. In this paper, we propose to build an energy transmission system on the traffic network and utilize electric vehicles (EVs) as energy carriers to transport energy from remote renewable sources to the loads. We construct a generalized architecture called the vehicular energy network (VEN) and develop a mathematically tractable framework for VEN. Dynamic wireless (dis)charging allows electric energy, as an energy packet, to be added and subtracted from EV batteries seamlessly. With proper routing, we can transport energy from the sources to destinations through EVs along appropriate vehicular routes based on the information via the vehicular ad-hoc network. This paper gives a proof-of-concept study of VEN with important related issues discussed. We illustrate the capability available with VEN using real traffic data in the United Kingdom. Our implementation shows that a substantial amount of renewable energy can be transported from remote wind farms to London under some reasonable settings. VEN can complement the power network and enhance the overall power transmission.
