| 摘要: |
| 电力系统碳排放计量是明确各环节排放责任、制定减排措施、实现碳中和战略目标的重要基础。碳流理论基于潮流追踪原理，可实现电力系统碳排放因子的计算和碳排放责任的分摊。潮流计算结果是准确计算碳排放因子的基础，但其受到网络模型准确性的影响。当线路参数发生变化时，可能导致碳排放因子计算失准。为此，提出了考虑线路参数修正的电力系统碳排放因子计算方法。首先，分析了基于碳流理论的电力系统碳排放因子计算方法。然后，利用量测数据和改进牛顿-拉夫逊法修正线路参数，提出考虑线路参数修正的电力系统碳排放因子计算方法，并进一步讨论了线路的参数变化对节点碳排放因子的影响规律。最后，仿真结果验证了所提方法可有效提升碳排放因子计算的准确性。 |

| Abstract: |
| Carbon emission measurement in power systems is an important foundation for clarifying emission responsibilities across different sectors, formulating emission reduction measures, and achieving carbon-neutrality goals. Carbon flow theory, based on the power flow tracking principle, enables the calculation of carbon emission factors and the allocation of carbon emission responsibility within power systems. Since accurate power flow results are fundamental to precise carbon emission factor calculation, their accuracy is affected by the fidelity of the network model. Variations in transmission line parameters may result in significant errors in carbon emission factor computation. To address this issue, a carbon emission factor calculation method considering line parameter correction is proposed. First, the carbon emission factor calculation method based on carbon flow theory is analyzed. Then, by using measurement data and an improved Newton-Raphson method to correct line parameters, a carbon emission factor calculation method that incorporates line parameter correction is developed. Furthermore, the influence of line parameter variations on nodal carbon emission factors is examined. Finally, simulation results verify that the proposed method can effectively improve the accuracy of carbon emission factor calculation. |
