| description | As renewable energy installation scales up, traditional carbon capture combined heat and power plants face challenges such as low carbon capture efficiency and inadequate regulatory capacity due to their heating supply obligations. In order to promote renewable energy integration and reduce carbon emissions while enhancing the peak regulation capabilities of these plants, this study constructs a joint operational model integrating hydrogen energy storage with oxy-fuel combustion carbon capture units, focusing on low-carbon economic dispatch. The paper first investigates the coordination mechanisms of oxy-fuel combustion carbon capture and hydrogen energy storage, establishing a system architecture. It then considers oxygen production from air separation and oxygen recovery from hydrogen storage, developing separate models for oxy-fuel combustion carbon capture units and hydrogen energy storage systems. Finally, leveraging carbon trading and peak regulation auxiliary service markets to enhance carbon reduction and peak regulation initiatives of power plants, the study aims to optimize system operating costs, establishing a low-carbon economic dispatch model for oxy-fuel combustion carbon capture plants integrated with hydrogen energy storage. Case study results demonstrate that the proposed model not only effectively improves system carbon efficiency and economic performance but also enhances the regulatory capabilities of combined heat and power plants, facilitating renewable energy integration. |
