Interactive Management Strategy of Virtual Power Plants Based on Carbon Demand Response

Household energy consumption continues to rise as the living standards of residents improve, making household carbon emissions a major contributor to global carbon emissions. Aiming at a low-carbon management strategy for the virtual power plants (VPPs), this paper estimates household carbon emissions based on dynamic carbon emission factors that can accurately reflect differences in carbon emissions generated by electricity, which can accurately reflect the difference of carbon emissions generated by electricity and heat consumption in each period. On this basis, a carbon demand response mechanism was established to guide users to adjust their energy consumption plans according to the carbon emission intensity of energy consumption in different periods. The coordinated load plan influences the VPP scheduling plan and achieves the interaction between supply and demand. According to the simulation results, compared with the traditional integrated demand response (IDR) mechanism, the carbon emissions of this method are reduced by 9.3%, and the energy supply cost is reduced by 18.9%, which shows that the CDR mechanism proposed in this paper can effectively reduce the carbon emissions and energy supply cost of the system.
