摘　　要：文章对碳捕集和电转气技术耦合下的电-热-气多能互补系统进行协同规划。通过系统动力学构建了碳捕集和电转气设备在电-热-气系统的关系图,并设计多能互补系统运行架构。在碳捕集和电转气技术耦合模型的基础上,建立了考虑这两种设备的电-热-气多能互补系统的多目标运行与规划协同优化模型。为验证模型的有效性,以某工业园区为例,采用NSGA-II算法对所建模型进行求解,使前期规划与后期运行有效结合,通过模糊隶属度函数从帕累托前沿中选择折衷解,确定规划方案和运行策略。模拟结果表明,与帕累托解集中的其他方案相比,文章方案以1.224亿元的较低成本减少了60%的直接排放,可再生能源消纳率达到93.36%,同时提供78.30%的燃气供应,较好地实现了经济和环境效益的平衡。Current research on carbon capture system and power to gas focuses on their own operation optimization.This paper discussed collaborative planning of electricity-thermal-gas multi-energy system with carbon capture and power to gas.We constructed the causality diagram of these two devices in the electric-thermal-gas system by using system dynamics,and put forward the structure of the multi-energy system.Through the coupling of carbon capture system and power to gas,a collaborative multi-objective optimization model for operation and planning is proposed.To verify the effectiveness of the proposed model,NSGA-II algorithm is used to solve the model,and the fuzzy membership function is adopted to select the compromise solution from the Pareto frontier,and the planning scheme and operation strategy is determined.The simulation results show that the selected scheme achieves 60%carbon abatement,93.36%renewable energy consumption rete,and 78.30%gas supply with 122.4 million yuan.
