Abstract

To enhance carbon capture levels during peak load periods and reduce excessive energy consumption, a dynamic carbon quota-based carbon capture and generalized energy storage model is proposed. Initially, comprehensive and flexible carbon capture devices were retrofitted onto high-carbon thermal power units, effectively lowering carbon emissions and increasing the system's low-carbon benefits. Secondly, a dynamic carbon quota model and dynamic carbon emission factor are introduced to guide and improve the output level of carbon capture units under high energy consumption conditions. Furthermore, pumped storage and electricity price-based demand response constitute generalized energy storage technology auxiliary regulation to alleviate the peak load pressure on thermal power units and carbon capture equipment. Finally, aiming at the optimal economy of the system, the output schedules of different units at different time periods were optimized. The low wind curtailment and load loss rates, as well as the operational economy of the carbon capture-generalized energy storage power system were verified by simulation under the dynamic carbon quota model.
