Low-Carbon Dispatch of Distribution Networks Considering Demand Response and Photovoltaic Integration

In the context of low-carbon electricity, the low-carbon operation of the distribution network significantly impacts the reduction of carbon emissions in the power system. Addressing how to achieve coordinated low-carbon economic operation at the distribution network level is an urgent issue that requires resolution. This paper proposes a low-carbon scheduling model that considers carbon emissions and demand response within the distribution network. First, we introduce an improved dynamic carbon emission factor for the distribution network, which serves as a guiding signal to provide reference for users' low-carbon electricity consumption. Next, we develop two distinct demand response models: one for industrial users aimed at minimizing scheduling costs while reducing carbon emissions, and another for residential users focused on electricity satisfaction and low-carbon satisfaction. Finally, simulations are conducted using an improved IEEE-33 node distribution system. The results indicate that the proposed scheduling model effectively reduces carbon emissions in the distribution network and enhances the integration of photovoltaic resources.
