A multi-microgrid electricity-carbon-green certificate coupling trading method

Multi-microgrid transactions are mostly oriented to pure economics while ignoring carbon emission benefits, and the electricity-carbon-green certificate transactions of multi-microgrids lack an effective bridging mechanism, a multi-microgrid electricity-carbon-green certificate coupling with improved Shapley-value method considering low-carbon benefits is designed to address the above problems. Firstly, in order to realize multi-microgrid resource mutual aid, reduce system operation cost and the docking of the carbon-green certificate market, a multi-microgrid resource mutual aid framework is established, and in the transaction model, the maximization of social welfare is taken as the goal; secondly, a microgrid optimization operation model is established, and the model takes the minimization of operation cost as the goal; and then, a social welfare distribution system under the entropy-based corrected Improved Shapley value method is proposed again to take into account the the carbon reduction contribution factor of each microgrid as one of the considerations of the allocation weights, which improves the carbon emission and scenery consumption of multiple microgrids; finally, the effectiveness of the proposed method is verified by simulation analysis.
