摘　　要：针对可再生能源的消纳问题,研究可控负荷机制与电-热耦合网中的储能调控策略,构建综合灵活性资源模型优化系统的低碳运行。首先分析区域电网中差异化布局的工业负荷调控机制,基于城市能源网架电热耦合建立可控负荷及电-热储能调控模型;然后以经济成本、风光消纳及碳排放为指标构建综合效益模型,提出碳排放流动拓扑,描述依附于能量流的碳排放流信息;最后对IEEE 33节点电网和45节点热网耦合能源系统进行仿真,分析多元灵活性资源响应对系统综合效益的改善效果,并通过拓扑直观显示典型场景中电-热碳排放流动过程。结果表明发掘灵活性资源能够提升电热综合能源系统对风光能源的消纳裕度,验证了所提方法的合理性和有效性。The modern energy system is in the low-carbon transition stage.However,due to the randomness and volatility of renewable energy,it is difficult to integrate into the grid and the low-carbon process is limited.Integrated Energy Systems(IES)focus on meeting the demand for interaction between supply and demand.In recent years,increasingly resources on the load and energy storage side have begun to participate in the low-carbon operation of the system,but the resource synergy advantage has not been fully utilized,and there is a lack of analysis on the flow and transfer of carbon emissions in IES.To solve these problems,this paper proposes a low carbon optimization model of electric and heating integrated energy system considering the participation of flexible resources,analyzes the improvement effect of multiple flexible resources response on the comprehensive benefits of the system,and visually presents the flow process of electric thermal carbon emissions topologically,promoting the efficient consumption of low carbon energy in IES.First,analyze the industrial load regulation mechanism of differentiated layout in the regional power grid,and establish the model of cogeneration unit,electric heating equipment,electric/thermal energy storage and controllable load in the electric-thermal coupling system based on the urban energy grid.Then,a comprehensive benefit model is built with economic cost,wind and solar usage and carbon emissions as indicators,and a carbon emission flow topology is proposed to describe the carbon emission flow information attached to the energy flow.Finally,the electric-thermal coupling energy system is simulated to obtain the regulatory results of flexible resources and carbon emission flow information in different resource allocation scenarios.In this model,the improvement effect of flexible resource participation response on the comprehensive benefits of the system is analyzed from the perspective of economy and low carbon,and a more comprehensive evaluation model is formed by visualizing the
