摘要

为应对日益严重的环境和能源问题，碳减排相关研究已成为重中之重，碳排放流能够辨析碳要素的流动。以此为研究背景，提出一种计及站-网损耗分摊的区域综合能源系统碳排放流计算方法。依据双层结构热力系统等效变换规则，构建电-气-热网络统一结构模型。在此基础上，对区域综合能源系统网络损耗实现双向分摊，碳排放流损耗等效至管线两端节点，明确网络损耗对应碳排放责任的主体。针对能源站碳责任的界定问题，在考虑能源站损耗的碳排放流集线器模型基础上，推广至标准化矩阵碳排放流集线器，并采用区域综合能源系统碳排放流统一矩阵计算方法，实现站-网损耗分摊下的碳排放流计算和分析。算例结果验证了所提方法的合理性和有效性，网损的双向分摊和考虑能源站损耗的碳排放流集线器模型使发电侧和用户侧更加公平地承担对应的碳排放责任，分布式多类型可再生能源的接入有利于提高全域新能源渗透率，降低站-网综合碳排放流损耗。

Abstract

In response to increasingly serious environmental and energy issues

the research on carbon emission reduction has had a top priority

and the carbon emission flow can distinguish the flow of carbon elements. Based on this research background

a calculation method for carbon emission flow in regional integrated energy systems considering station-network loss allocation is proposed. According to the equivalent transformation rules of double-layer thermal system

the unified structure model of electricity-gas-thermal network is established. On this basis

the network loss of the regional integrated energy system is allocated in both directions

and the carbon emission flow loss is equivalent to the nodes at both ends of the pipeline

and the main body of the carbon emission responsibility corresponding to the network loss is defined. Aiming at the definition of the carbon responsibility of energy stations

based on carbon emission flow hub model considering the loss of energy stations

it is extended to the standardized matrix carbon flow hub. And the unified matrix calculation method of carbon emission flow of regional integrated energy system is adopted to realize the carbon emission flow calculation and analysis under the allocation of station-network loss. The case results verify the rationality and effectiveness of the proposed method. The bidirectional allocation of network losses and the carbon emission flow hub model considering energy station losses enable the generation and user sides to more equitably bear the corresponding carbon emission responsibilities. The integration of distributed multi-type renewable energy is beneficial for improving the penetration rate of renewable energy in the entire region and reducing the comprehensive station-network carbon emission flow loss
