Under the influence of domestic dual carbon targets, international green trade barriers, the demand for carbon reduction on the user side has sharply increased. As an important bridge connecting new power systems and electricity loads, microgrids can effectively balance local distributed energy output and promote green and low-carbon transformation on the user side, meeting their carbon reduction needs. The economic operation strategy of microgrids considering the demand for carbon reduction is mainly studied. Firstly, a microgrid operation model that includes wind and solar power, energy storage, electric vehicles, and flexible loads is constructed. Then carbon emission costs and system operation costs are comprehensively considered to construct an optimization model. Finally, based on the CPLEX solving tool, the results show that the proposed method can adapt to fluctuations in new energy output, changes in electricity prices, and changes in carbon prices, meet the carbon reduction needs of users within the microgrid, and significantly improve the low-carbon economic operation level of the system.
