Economic Operation Modeling Analysis of Integrated Energy System Based on Integration of Wind-Hydrogen-Methanol-Carbon Capture

Aiming to address the challenge of wind power consumption and high storage costs in traditional hydrogen storage methods, an economic model for integrated energy systems based on the integration of wind-hydrogen-methanol-carbon capture was proposed to establish a safer and more economical hydrogen storage mode. First, a structural model of an integrated energy system (IES) was developed to replace the traditional hydrogen storage mode through a hydrogen to methanol and methanol reforming hydrogen production system. By Cooperating with carbon capture equipment, carbon resource recycling was realized. Secondly, the economic and environmental costs of the system operation were comprehensively considered, leading to the establishment of an economic operation model for the system. Finally, the feasibility of the proposed model was verified by comparing four operation scenarios.
