摘要
在“双碳”的背景下,为进一步提升综合能源系统(Integrated Energy System, IES)的经济性和环境效益,文中提出一种在奖惩阶梯型碳交易机制下考虑含热回收装置(Heat Recycling Device, HRD)的光热电站和综合需求响应的IES系统低碳经济调度方法。首先,在源侧构建含热回收装置的光热电站与加装碳捕集的热电联产机组联合运行的IES架构,并分析电转气两阶段的运行原理,建立计及余热回收的电转气设备模型。其次,考虑到负荷侧电、热、气三种负荷的柔性特性,在负荷侧建立电热气综合需求响应模型。最后,引入奖惩阶梯型碳交易机制,进一步减小系统碳排放量,构建调度周期内以含购能成本、运维成本、碳交易成本等系统总运行成本最小为目标的综合能源系统低碳优化调度模型。通过算例分析结果表明,所提方法不仅能提高机组的运行潜力,而且有效降低了系统总运行成本与碳排放量。
In the context of“dual-carbon”,in order to further enhance the economic and environmental benefits of integrated energy system,the paper proposes a low-carbon optimal scheduling methodology for IES under the reward-penalty ladder-type carbon trading mechanism,taking into account a photovoltaic power plant with heat recovery device and integrated demand response.Optimal scheduling method.Firstly,the IES architecture for the joint operation of a photovoltaic power plant with heat recovery device and a cogeneration unit with carbon capture is constructed on the source side,and the operation principle of the two stages of power-to-gas conversion is analysed to establish a model of power-to-gas conversion equipment taking into account the waste heat recovery.Secondly,considering the flexible characteristics of the three loads of electricity,heat and gas on the customer side,an integrated demand response model for electricity,heat and gas is established on the load side.Finally,the carbon trading mechanism is introduced to further reduce the carbon emissions of the system,so as to construct a low-carbon optimal dispatch model of the integrated energy system with the goal of minimising the total operating costs of the system,including the energy purchase cost,operation and maintenance cost,and the carbon trading cost,during the scheduling cycle.The results of the analyses show that the proposed method not only improves the operating potential of the units,but also effectively reduces the total system operating costs and carbon emissions.
