考虑电储能设备碳排放的综合能源系统低碳经济运行

为了减少综合能源系统发电过程中产生的碳排放造成的环境污染,必须提升综合能源系统的经济效益.除各发电机组设备存在大量碳排放外,电储能设备的间接使用过程中也存在较大的碳排放,应当计量在系统碳排放中.研究基于含电气热冷负荷需求的综合能源系统,分析系统中各机组设备的碳排放量,并运用生命周期分析方法,分析系统中电储能设备产生的碳排放,在系统经济运行模型中考虑碳交易机制,通过改进的鲸鱼优化算法对模型进行求解.在保证系统负荷需求的前提下,对根据是否计及电储能设备碳排放情况下的综合能源系统各机组出力情况对比分析.结果表明,在低碳权重作用大时,计及电储能设备碳排放能够有效降低综合能源系统运行成本,同时减少碳排放总量.

Low carbon economy operation of integrated energy system considering carbon emission of energy storage systems

In order to reduce the environmental pollution caused by carbon emissions in the process of power generation of the integrated energy system, and improve the economic benefits of the integrated energy system. In addition to a large amount of carbon emissions from various generator units, there are also large carbon emissions in the indirect use of energy storage systems, which should be measured in the system carbon emissions. Based on the integrated energy system with electric heating and cooling load demand, the carbon emission of each unit in the system is analyzed, and the carbon emission generated by the energy storage systems in the system is analyzed by using the life cycle assessment method, which is combined with the carbon trading mechanism model into the system economic operation model, and the model is solved by the improved whale optimization algorithm. On the premise of ensuring the load demand of system, the comparative analysis of the output of each unit of the integrated energy system based on whether the carbon emission of the energy storage systems is taken into account shows that the carbon emission of the energy storage systems can effectively reduce the operation cost of the integrated energy system and the total carbon emission when the carbon emission of the energy storage systems is taken into account.
