| Abstract: |
| Carbon peaking and carbon neutrality goals" puts forward new requirements for low-carbon and high-efficiency integrated energy systems. Aiming at the joint programming problem of source-network-load-storage of the park-level integrated energy system, the programming model of maximizing the net income of the system based on the Bellman optimal theory was decomposed, and a multi-stage dynamic programming model of "wind-solar-storage synergy-multi-energy interconnection coupling-energy consumption hydrogen production-optimal carbon capture" was established, and the optimal configuration scheme of the equipment was solved. The results show that the model has significant advantages in the aspects of economy and environmental protection. The benefits of electric hydrogen production are considerable and the local consumption of electric energy is promoted. Carbon capture reduces the carbon emissions of the system and achieves the dual benefits of selling CO2 gas and carbon quota. At the same time, the optimal configuration of electric hydrogen production and the optimal carbon capture ratio are achieved in the process of dynamic programming. |
