基于电制氢多级利用的综合能源系统低碳经济运行优化研究
Research on low-carbon economic operation optimization of integrated energy systems based on multi-level utilization of hydrogen production from electricity
摘要
Abstract
Driven by the"dual-carbon"goals,developing efficient and low-carbon integrated energy systems has become a critical priority.To address the issue of high carbon emissions,high operating costs,and low energy utilization efficiency of integrated energy systems,an optimization model for low-carbon economic operation of integrated energy systems was proposed based on multi-level utilization of hydrogen production from electricity.By integrating two-stage power-to-gas technology with carbon capture and storage technologies,carbon recycling within the system was achieved.Based on this,a multi-level utilization system for hydrogen production from electricity was established,which included methane production,hydrogen blending in natural gas,and hydrogen storage,thus improving hydrogen utilization efficiency.By incorporating the tiered carbon trading mechanism,an optimization model with the goal of minimizing total operating costs was developed.Case analysis showed that the optimization model improved hydrogen utilization efficiency by 8.2%,promoting the multi-level utilization of hydrogen.The total operating cost and carbon emissions were reduced by 7.58%and 10.1%,respectively,effectively promoting the low-carbon economic operation of the integrated energy system.关键词
