Multiplayer Energy Trading Framework of the Shared Alliance Based on Nash Negotiation

The energy sharing business model of "self-balance + energy mutual aid" can enhance the friendly grid connection capacity of renewable energy, in some regions. This Shared Alliance model is one of the feasible and optimal pathways to achieve China's double control targets of carbon intensity and carbon emissions peak from the perspective. However, the traditional energy trading limits the large-scale progress of energy trading among multi participants for CO-governance and restricts the willingness of more players to enter the Shared Alliance. In this regard, a Shared Alliance multiplayer energy trading strategy based on Nash negotiation is proposed. A general model framework for the trading strategy including energy storage, multi microgrid group, and the superior power grid is established. Based on Nash negotiation theory, the model constructs a cooperative and competitive energy market transaction of multiple suppliers and multiple buyers and shares the surplus electricity of each player through the sharing platform. The simulation results show that the energy sharing model can give full play to the initiative of the demand-side and improve the utilization of energy storage based on ensuring the benefits of all players.
