Under the “dual carbon” goals,microgrids (MGs),as a critical component of distributed energy aggregation and optimized operation in new power systems,have garnered significant research interest for their resource interaction capabilities. Accordingly,this paper proposes an optimal scheduling strategy for multi-MG systems with resource sharing,incorporating a dynamic carbon credit trading mechanism. First,a dynamic carbon credit trading mechanism is established to incentivize effective energy interaction and resource sharing among MGs. Second,a cooperative game model for multi-MG resources considering the dynamic carbon credit trading mechanism is developed based on asymmetric Nash bargaining theory. Finally,an improved alternating direction method of multipliers (ADMM) is employed for distributed solution,enhancing convergence speed while preserving the privacy of each entity. Simulation analysis demonstrates that the proposed strategy improves the local consumption rate of renewable energy and achieves low-carbon economic operation of the system.
