Research on Optimal Operation of Multi-Energy Complementary Zero-Carbon Community Microgrid

As the global greenhouse gas problem intensifies, the phenomenon of excessive carbon emissions from communities has aroused widespread concern in the international community. The carbon emission of the community mainly comes from its energy system. Building a low-carbon and high-efficiency energy system is the key to achieving carbon emission reduction in communities. In order to meet the diversified load demand of the community, this paper proposes a multi-energy complementary zero-carbon microgrid structure incorporating multiple heat pump technologies along with its optimal operation method. The optimization approach aims to minimize the daily total operating cost of the microgrid, with the daily generation scheduling of each equipment unit as optimization variables, and uses the ant colony optimization algorithm to calculate the optimal operation scheme of the microgrid. Finally, the effectiveness and economy of this method are validated by case analysis.
