An Interaction Collaborative Low-Carbon Scheduling of Multi-microgrid Distribution System with Carbon Trading Mechanism

In order to promote the low-carbon development of power systems, this paper proposes an interaction collaborative low-carbon scheduling model of multi-microgrid distribution systems (MMDS) with carbon trading mechanism. In this model, a cooperative operating structure of multi-microgrid (MMG) and distribution network (DN) based on power interaction is established, in which different microgrids with different energy supplies share electricity with each other through contact lines, and each microgrid (MG) is connected to the DN in a decentralized manner to interact with it. To reduce the carbon emissions of the system, this paper adopts the carbon emission reward and punishment operation mechanism. By this means, MMG and DN can reap economic benefits in the carbon market through energy savings and emissions reductions. Finally, the numerical results show that the proposed strategy can significantly promote the comprehensive utilization of energy and make full use of its multi-energy complementarity advantages. At the same time, it can also promote the low-carbon economic operation of the MMDS.
