In the upper layer, a Stackelberg game model is established, in which SES acts as the leader maximizing profit by offering electricity prices, while the alliance of prosumers is the follower responding to the prices through demand response and peer-to-peer (P2P) energy exchange. In the lower layer, a cooperative game is constructed for the prosumer alliance, the contributions of individual prosumers are scored and the asymmetric Nash bargaining is utilized to fairly allocate the total expense within the prosumer alliance. The alternating direction method of multipliers (ADMM) is adopted for privacy protection.

The day-ahead energy sharing problem is decomposed into energy sharing scheme formulation problem and energy sharing benefits settlement problem. To meet the privacy protection requirements of service providers, these problems are addressed by parallel distributed optimization algorithm. In sharing benefits settlement problem, a non-linear mapping function is proposed to calculate bargaining weights of service providers and distribute sharing benefits. Finally, simulation results show that the energy sharing strategy can maximize the benefits of each integrated service provider and the sharing alliance of them. With the fair distribution of sharing benefits, the sharing strategy incentivizes the active participation of service providers in sharing.

The paradigm eliminates conventional manual tuning problems through gradient-aware exploration of non-convex landscapes, resolving the trade-off between fidelity and measurement noise adaptation.
