In order to ensure stability of the power grid and satisfy the Quality of Energy (QoE) requirements of Electric Vehicles (EVs), this paper proposes a two-level group bidding mechanism for the electric energy trade between the grid and EVs. Communication networks are used to support the exchange of relevant information between the grid and EVs. EVs act as mobile energy storage and compete to be one of the members in the electricity feedback group organized by aggregators. We aim at minimizing the cost of given electricity demand of the grid and maximizing the profit of those auction winner EVs. A quantity based feedback electricity unit pricing scheme is proposed to incentivize the participation of EVs in V2G networks. Moreover, Vickrey-Clarke-Groves (VCG) auction-based algorithms are designed to implement our proposed mechanisms. Simulation results indicate that our mechanism is able to reduce the cost of the grid while offer EVs significant incentives to participate inthe V2G power market.}, year = {2015}, journal = {IEEE International Conference on Communications}, month = {06/2015}, publisher = {IEEE}, address = {London, UK}, }
