中国电力行业传统的碳排放计量都是以电源为排放源，这种计量方式没有考虑电力的传输过程，用户也无法直观感受到自身消费行为引起的碳排放。为了鼓励绿色电力的接入，明确用户消费电能产生的碳排放量，促进绿色电力证书市场的发展，有必要从用户侧进行碳排放计量。文中在计及网损的复功率潮流追踪模型基础上建立了碳流追踪模型，将无功功率对于有功功率的间接作用通过共同追踪的方式体现，全面分析了电力网络中二氧化碳伴随功率从电源侧向用户侧的“流动”。通过 IEEE 57节点算例检验了碳流追踪模型的正确性，碳流追踪结果可以计量引入绿色电力后用户侧各节点以及全网网损的减排比例，亦可为各区域间减排责任的划分提供依据。同时，线路网损产生的碳排放量为低碳电力调度提供了新的参考。

The traditional carbon emission calculation in power industry treats power source as emission source to the neglect of the power transmission process and making it impossible for consumers to directly perceive their carbon emission information through electricity consumption.It is thus necessary to measure carbon emission based on demand level to encourage green power access,calculate consumers” carbon emission and benefit the promotion of green power certificates market.A carbon emission flow tracing model capable of reflecting the indirect effect of reactive power on active power via joint tracing is proposed.The correctness of the proposed model is verified by an IEEE 57-bus system.Nodal emission cuts proportion after introduction of green power can be measured through carbon flow tracing while providing a basis for the allocation of responsibilities for emission reductions between regions.And the carbon emission generated by power losses should be a new reference to low-carbon power dispatch.
