| Summary: | The new energy system is a component and a key carrier for achieving the goal of “carbon peak/carbon neutrality”. Carbon emission flow tracking helps to clarify the carbon emission responsibility and provides important data support and decision-making basis for realizing the dual-carbon target. In view of this, a novel model is proposed to analyze the carbon emissions of units and loads within the power system. Firstly, the parameters at each node and branch are calculated using the Newton-Raphson method based on the nodal load data, generator power output, and so on. Secondly, the real-time carbon emission intensity model between different units is established considering the unit characteristics and fuel attributes. Then the power flow distribution matrix as well as the unit carbon emission injection intensity matrix are constructed, which are used to allocate the generator power to each node load, branch power and network loss, so as to obtain the corresponding power components. On this basis, the actual carbon consumption of the unit as well as the load in the corresponding period is calculated. The approach above makes it possible to characterize the distribution of carbon emission contributions within the system. By tracking power flow, an accurate quantification of the carbon emissions caused by network losses is achieved, which in turn provide an immediate allocation result for the system’s carbon emissions. Finally, the validity, accuracy and generalizability are verified in IEEE 5-bus and IEEE 39-bus standard systems. In addition, the application of the power flow tracking green certification model for green power traceability is prospected. |
