An Electric Taxi Charging Guidance Approach for Transactive Energy Sharing with Energy Community

With the development of electric vehicles. an ever-increasing coupling of energy and mobility sectors is underway. Meanwhile, electric taxis (ETs), as the main participants in the traffic-grid coupling network, have not been effectively guided for their charging behavior. Thus, this paper introduces a novel E-taxi with charging guidance platform (ETCGP), which can guide the ET to the designated energy communities (ECs) for charging under the transactive energy framework. Firstly, with the fulfillment of the passenger traveling needs, a travel-charging order matching model of ETCGP using the matching degree matrix is proposed for charging guidance. Then, an EC-ETCGP cooperation model based on the Nash bargaining theory is constructed. To solve this problem, this model is decomposed into EC-ETCGP alliance benefit maximization sub-problem and payment bargaining sub-problem. The former one is solved with a centralized approach to obtain the optimal energy exchange between the EC and ETCGP, while the latter one applies an alternating direction method of multipliers method to determine the trading prices. Finally, the simulation results show that the benefits of both the EC and the ETCGP can be significantly increased by the proposed transactive energy sharing method.
