Optimal Energy Management for Mutil-energy Microgrid Considering Ladder-Type Carbon Emissions Trading

To meet the challenge of global low-carbon development, the low-carbon operation mode for the microgrid is the research hotspot at present. In this paper, optimal energy management for multi-energy microgrid (MEMG) considering ladder-type carbon emissions trading is proposed. Based on energy conversion and multi-energy storage devices, the electricity-heat-gas hybrid MEMG structure is constructed. Then considering a ladder-type carbon emissions trading mechanism, a MEMG low-carbon day-ahead scheduling model is established to minimize the daily operation costs and carbon emissions trading costs. To validate the effectiveness of the proposed MEMG energy management method, a test day analysis is conducted. Our findings demonstrate the significant benefits derived from this approach in achieving efficient and low-carbon operation of MEMGs.
