Optimal Scheduling of Integrated Energy System Considering Source-Load Uncertainty

With the formulation of policies related to the "double carbon" target, the construction of a low-carbon and environmentally friendly Integrated Energy System (IES) has become a hot research topic today. An scheduling model is proposed that takes into account the synergy between power-togas (P2G) and carbon capture. By introducing a framework for the synergistic use of carbon capture power plants (CCPP) and P2G equipment, the high concentration of carbon dioxide (CO2) captured is used as feedstock for P2G equipment, and a Carbon Storage Device (CSD) is proposed to solve the time mismatch between the capture and use of CO2. The interval optimization method is applied to address the uncertainty in the supply and consumption of energy, with the aim of improving the safe and efficient operation of the system. Simulation results show that the proposed model reduces carbon emissions and wind abandonment and achieves low carbon economic dispatch(LCED) of the IEGS.
