Nash Negotiation Based Multiplayer Energy Trading Framework for Shared Alliance

The energy-shared alliance model with multiple players is one of the feasible and optimal pathways to improve resource utilization without requiring costly and time-consuming infrastructure investments. However, the traditional energy trading method is not suitable for the Shared Alliance model due to it limits the large-scale progress of energy trading among multiple participants for CO-governance and restricts the willingness of more players to enter the Shared Alliance. This paper studies the energy trading strategy for the Shared Alliance multiplayer based on Nash Negotiation. An energy-sharing framework is established which contains energy storage, multi-microgrid groups, and the superior power grid. The cooperative and competitive energy market transaction mechanism of multiple suppliers and buyers is constructed by Nash negotiation theory, the surplus electricity of each participant is shared through the transaction mechanism. The numerical simulation is carried out to verify the effectiveness of the proposed method. The results show that the proposed model can give full play to the initiative of the demand side and improve the utilization of energy storage. Such research delivers abundant technical support for energy complementarity among multi-participants and provides sustainable development of energy-sharing mechanisms.
