Low carbon optimal dispatching of power system considering carbon emission flow theory

In the context of the multiple objectives of carbon peaking, carbon neutral and the construction of modern power systems, how to further achieve the energy saving and emission reduction goals of the system while ensuring the rationality of schedule is an important issue that needs to be addressed. To address the problems that the current research on power scheduling does not integrate the carbon emission flow with the power flow, a low-carbon optimal scheduling method for power systems that took into account the carbon emission flow theory was proposed. Firstly, a carbon emission flow model of the power system was constructed at the equipment level and the system level respectively. Secondly, a bi-level alternating optimal scheduling model, which includes system day-ahead scheduling and load demand response adjustment, was established by considering all aspects of the power system from source-grid-load-storage. Finally, the effectiveness and applicability of the proposed theoretical approach in reducing operating costs and carbon emissions were verified through real-life simulations.
