Interactive Energy: an Approach for the Dynamic Pricing and Dispatching of EV Charging Service

The paper proposes a new idea, called "Interactive Energy", for the dynamic pricing and dispatching of the charging services of Electric Vehicles (EVs) in a micro-grid. In the proposed approach, the customers can choose their recharge time through an interactive application able to indicate different recharge times and related prices in function of the real time conditions of the micro-grid. The available power at each charging station is conditioned to the grid conditions and the prices change as a function of the requested energy, power and local renewable energy produced in the micro-grid. In the paper, a statistical model is proposed and applied for analyzing the impact that the proposed system can have on the power grid. The proposed system can gain ground with the ongoing battery improvements: the recharging times for EVs could become comparable to the present fuel stop times at the gas station through the continuous improvement of the battery technologies.
