摘要

针对综合能源系统损耗碳排放责任在源荷主体间分摊不清的问题，提出一种基于㶲的能源转换设备碳排放分摊模型，以及一种基于潮流追踪的综合能源系统网损碳排放责任分摊方法。提出计及㶲损的能源转换设备碳排放分摊模型，将㶲损对应的碳排放责任基于可调参数分摊给能源转换设备本身及其输出能流；对于具有多类型输出的能源转换设备，基于㶲分摊法，将输出能流碳排放在不同类型输出能流间进行分摊，得到不同类型能流的碳排放强度；根据能源转换设备碳排放分摊模型以及电-热-气网潮流模型，基于潮流追踪法，获取网损源荷双向分摊的统一矩阵计算公式，将电-热-气网的网损基于可调参数分摊给源端和负荷端，进而求解得到源端和负荷端的网损碳排放责任。算例结果验证了所提模型和方法的有效性和合理性，综合能源系统损耗碳排放责任的精细合理分摊，有助于准确追踪与溯源碳排放流，提高各主体的碳排放责任意识，降低系统碳排放。

Abstract

Aiming at the unclear allocation problem of carbon emission responsibility for loss in integrated energy system among energy source and load，an exergy-based carbon emission allocation model for energy conversion equipment and a power flow tracking-based carbon emission responsibility allocation method for loss in integrated energy system are proposed. A carbon emission allocation model for energy conversion equipment is introduced considering the exergy loss，which allocates the carbon emission responsibility corresponded to the exergy loss to the energy conversion equipment and its output energy flow based on an adjustable parameter. Aiming at the energy conversion equipment with multiple output types，the output energy flow carbon emission is allocated among different types of output energy flow based on the exergy allocation method，which obtains the carbon emission intensity of different types of energy flow. According to the carbon emission allocation model of energy conversion equipment and the electricity-thermal-gas power flow model，a unified matrix calculation equation for bidirectional allocation of network loss between source and load is derived based on the power flow tracking method，the electricity-thermal-gas network loss is allocated to the source and load terminals based on the adjustable parameters，thereby the carbon emission res-ponsibility for loss at the source and load terminals are obtained. The example results verify the effectiveness and rationality of the proposed model and method. The refined and rational allocation of carbon emission responsibility for loss in integrated energy system is helpful for accurately tracking and tracing the carbon emission，enhances the carbon emission responsibility awareness of each entity，and reduces the system carbon emission.
