Vehicle-to-grid provides a viable approach that feeds the battery energy stored in Electric Vehicles (EVs) back to the power grid. Meanwhile, since EVs are mobile, the energy in EVs can be easily transported from one place to another. Based on these two observations, the authors introduce a novel concept called EV energy network for energy transmission and distribution using EVs. They present a concrete example to illustrate the usage of an EV energy network, and then study the optimization problem of how to deploy energy routers in an EV energy network. They prove that the problem is NP-hard and develop a greedy heuristic solution. Simulations using real-world data shows that their method is efficient.
