摘要
为突破电-气耦合能源系统(integrated electricity-gas system,IEGS)安全分析中碳排放流建模不足的局限,探索以碳流视角为核心的系统安全监视理论与方法,提出IEGS碳排放安全域(carbon emission security region,CESR)的概念、模型和计算分析方法。首先,构建满足N-0安全约束下的IEGS的CESR模型;其次,解析CESR与能流安全域(energy flow security region,EFSR)的数学耦合关系,并讨论CESR与EFSR在高维空间中的几何关联特性;然后,建立系统碳排放能力极限模型;进而,提出CESR安全边界概念与可视化降维观测方法;之后,探究碳排放能力与供能能力的数学关系,表明碳排放能力与供能能力并非简单的等比例线性关系,需针对IEGS拓扑结构及运行工况具体分析;最后,通过算例验证表明所提模型的有效性,并结合算例提出了同碳最大供能能力、同供能最小碳排放能力的概念与计算模型,为“双碳”目标下IEGS的安全-低碳-高供能协同调度提供理论支撑与决策工具。
To address the limitations of carbon emission flow modeling in the safety analysis of integrated electricity-gas system(IEGS)and explore system security monitoring theories and methods centered on a carbon flow perspective.This paper proposes the concept,model,and computational analysis of the carbon emission security region(CESR)for IEGS.First,the CESR model for IEGS under N-0 security constraints is established.Subsequently,the mathematical coupling mechanism between CESR and the energy flow security region(EFSR)is investigated,with geometric correlations in high-dimensional space analyzed.Next,a quantitative model for system total carbon emission capacity limits is developed.Furthermore,the concept of CESR security boundaries and a visual dimensionalityreduction observation method are proposed.Furthermore,the mathematical relationship between the carbon emission capacity and the total supply capability is explored,revealing that it is not a simple proportional linear relationship and must be analyzed specifically for the topology and operational conditions of the individual IEGS.Finally,case studies validate the effectiveness of the proposed model,the concepts and computational frameworks of the maximum carbon-constant total supply capability(MAX_CTSC)and minimum supplyconstant total carbon emission capacity(MIN_STCE)are established based on these studies.This work ultimately provides theoretical foundations and decision-making tools for achieving security-low carbon-high supply synergy of IEGS under the"dual carbon"goals.
