In this article, an operational framework is proposed for peer-to-peer (P2P) energy trading between a group of electric vehicles (EVs) within a charging station and a business entity equipped with solar generation that will significantly improve the benefit of all parties compared to having sole agreements with the utility. A dynamic pricing mechanism for the EVs is developed based on the price of the stored energy that not only increases owners' profit but also promotes the contribution of charging stations in P2P energy markets. To evaluate the proposed framework, the performance of the system under P2P energy sharing is compared with peer-to-grid (P2G) energy trading. The results show a 23.24% reduction in total cost of prosumers and an improvement of 10% in self-consumption of Photovoltaics (PV) generation as well as 100% participation willingness of prosumers. The results also suggest that considering the availability of solar energy during daylight hours and the possibility to trade the stored energy in EVs outside of home, P2P energy transactions under the proposed control framework will bring significant economic benefits for EV owners.
