The Interaction Research of Smart Grid and EV Based Wireless Charging

As an important part of the smart grid, Electric Vehicles (EVs) could be a good measure against energy shortages and environmental pollutions. By wireless charging technology, the interaction between EVs and the grid could be achieved without physical link. In this paper, the interaction capability of the EVs based wireless charging and the smart grid is mainly studied. The results of numerical simulations show that the EVs based wireless charging could better absorb renewable energy and reduce the impact of large-scale EVs application on the power distribution system. Finally, a four-layer framework of V2G system is designed for the EVs based wireless charging.
