基于生命周期法和碳权交易的综合能源系统低碳经济调度

Low-carbon economic dispatch of integrated energy system based on life cycle method and carbon trading

随着综合能源系统的不断发展,如何进一步提升综合能源系统的经济和环境效益是综合能源系统的重要研究内容。除了各发电机组存在大量的碳排放外,新能源机组及电储能设备生产建设和运输过程也存在大量碳排放,也应计入系统的总碳排放量中。为此文中基于含电热负荷需求的综合能源系统,分析了系统各机组的碳排放量,并运用生命周期法分析综合能源系统中新能源机组及电储能设备生产建设和运输过程所产生的碳排放量,将其与碳权交易联合引入综合能源系统的经济决策指标中,通过CPLEX对系统模型进行求解。最后通过对是否计及风电和电储能设备碳排放的综合能源系统两种算例对比分析。结果表明,将生命周期法与碳权交易引入综合能源系统可以促进综合能源系统的低碳化发展。

With the continuous development of the integrated energy system,how to further improve its economic and environmental benefits is an important research content of the integrated energy system.In addition to the large amount of carbon emissions in each power generation unit,there are also large amounts of carbon emissions in the production,construction and transportation of new energy units and electric energy storage equipment,which should also be included in the total carbon emissions of the system.For this reason,this paper analyzes the carbon emissions of each unit of the system based on the integrated energy system with electric heating load demand,and uses the life cycle method to analyze the carbon emissions generated during the production,construction and transportation of new energy units and electric energy storage equipment in the integrated energy system.Emissions are introduced into the economic decision-making indicators of the integrated energy system jointly with carbon rights trading,and the system model is solved through CPLEX.Finally,a comparative analysis of two calculation examples of the integrated energy system,whether the carbon emissions of wind power and electric energy storage equipment are taken into account,is compared and analyzed.The results show that the introduction of life cycle method and carbon rights trading into the integrated energy system can promote the low-carbon development of the integrated energy system.
