| 摘要: |
| 区域尺度多流传输的空间碳转移分析有助于碳排放量的准确计量。基于节点流模型在省级层次上开展碳转移评估。针对单流的传输，提出单流多节点碳转移评估模型，量化单流空间传输碳排放和碳转移；考虑多能源传输中耦合部分隐含碳的核算，在单流模型的基础上提出多流多节点的碳转移评估模型，测算多流输送的二级空间传递导致的各能流碳排放和碳转移，并对碳转移的主要影响因素进行敏感性分析。2017年中国省际天然气、电力和热力能流下的碳转移结果验证了所提模型的有效性。 |

| Abstract: |
| The spatial carbon transfer analysis of regional-scale multi-energy flow transport contributes to accurate measurement of carbon emission. The carbon transfer assessment is carried out at the provincial level based on the nodal flow model. A single-flow multi-node carbon transfer assessment model is proposed for transmitting a single energy flow, which quantifies the carbon emission and carbon transfer of single energy flow space transmission. Considering the accounting of implicit carbon in the coupled portion of multi-energy transmission, a multi-flow and multi-node carbon transfer evaluation model based on the single-flow model is proposed, the carbon emission and carbon transfer of each energy flow caused by the secondary spatial transfer of multi-energy flow transmission are calculated, and the sensitivity analysis of main factors affecting carbon transfer is carried out. The validity of the proposed model is verified by the carbon transfer results under the inter-provincial natural gas, electricity, and thermal energy flows in China in 2017. |
