A Study on Low-Carbon Dispatching of Multi-Microgrid Cooperative Game Considering Carbon-Green Certificate Joint Trading

In order to realize the low-carbon economic goal of multi-microgrid system, this paper proposes a cooperative game low-carbon dispatching model for multi-microgrid system considering carbon-green certificate joint trading. Firstly, the carbon emissions trading and green certificate trading are considered comprehensively to establish carbon-green certificate joint trading model; Secondly, combining Nash negotiation theory to consider carbon-green certificate joint trading into a cooperative game low-carbon scheduling model for multi-microgrids, and the model is solved by the improved ADMM algorithm, which can effectively ensure the fair distribution of benefits among multi-microgrid system, protect the privacy of each participant and improve the convergence speed. Finally, the case shows that the proposed model can realize the energy-saving and carbon-reducing utility of the multi-microgrid systems, while guaranteeing the distribution of benefits of each participating subject.
