Study on Operation Optimization of Integrated Energy System with Carbon Capture and Gas Hydrogen Blending Considering Green Certificate and Carbon Joint Trading

摘要: 碳捕集和燃气掺氢都是实现综合能源系统绿色低碳的重要手段之一，鼓励绿色能源发展的绿证配额制以及限制碳排放量的碳排放权交易制度在电力市场中应用广泛。为减少经济和碳排放的同时充分利用可再生能源，本文提出一种考虑绿证–碳联合交易的含碳捕集和燃气掺氢的综合能源系统运行优化研究。首先，引入碳捕集设备和燃气掺氢系统，降低碳排和系统成本，同时分析了掺氢比对碳排放的影响；其次，通过绿色证书交易机制与碳交易机制联合激励综合能源系统进一步绿色低碳，并分析了绿证配额系数对系统经济性、碳排放和可再生能源消纳的影响；最后构建不同场景下的综合能源系统运行优化研究，在Matlab中利用gurobi求解器求解。算例结果表明，本文所提出的模型能够有效提高系统的低碳性与经济性，并提高可再生能源的消纳量。

Abstract: Carbon capture and gas hydrogen blending are both important means to achieve green and low-carbon integrated energy system. The green certificate quota system to encourage the development of green energy and the carbon emission trading system to limit carbon emissions are widely used in the power market. In order to make full use of renewable energy while reducing economy and carbon emissions, this paper proposes an integrated energy system operation optimization strategy with carbon capture and gas hydrogen blending, which takes into account green certificate and carbon joint trading. Firstly, carbon capture equipment and gas hydrogen mixing system are introduced to reduce carbon emission and system cost, and the influence of hydrogen mixing ratio on carbon emission is analyzed; secondly, through the green certificate trading mechanism and carbon trading mechanism to stimulate the integrated energy system to further green low-carbon, and the effects of the green certificate quota coefficient on the system economy, carbon emissions and renewable energy consumption are analyzed; finally, a comprehensive energy system operation optimization strategy under different scenarios is constructed and solved by using gurobi solver in Matlab. The numerical results show that the proposed model can effectively improve the low carbon and economy of the system and increase the consumption of renewable energy.
