In order to realize the collaborative management problem of multi-microgrids (MMG)
and to balance the distribution of benefits between the distribution system operator (DSO) and each MG while guaranteeing low-carbon and economic operation of the system
this paper proposes a hybrid game strategy for multi-microgrids that considers electricity-carbon coupling trading. Firstly
a master-slave game model is constructed with the DSO as the leader and the MGs as the followers. Secondly
based on Nash bargaining theory
a cooperative game model between microgrids considering electricity-carbon coupling trading is constructed
and in the benefit distribution mechanism
the comprehensive contribution rate is used to ensure a fair and reasonable distribution of benefits. The distributed solution of this hybrid game is realized through the synergistic iteration of bisection method and alternating direction multiplier method (ADMM)
which improves the computational efficiency while ensuring the information privacy. Comparative analysis and case studies demonstrate that the proposed strategy can effectively enhance the benefits of each subject
reduce the carbon emissions of the system
and realize the fair distribution of benefits among microgrids.
