Abstract:
Objective Carbon emission factor is the key parameter of carbon emission accounting in power system. In the process of accounting, measurement methods are mostly adopted at the provincial level and above, with the year as the time unit scale. In view of the situation that the traditional carbon emission factor used in the accounting process cannot reflect the temporal and spatial differences and the characteristics of electricity consumption.
Method The study focused on the real-time carbon emission factor accounting method of provincial scale, with smaller time scale.
Result According to the daily load curves of different periods, based on the load model of thermal power plant units and the typical working conditions of new energy power stations, the regional carbon emission factors were calculated. The rationality of the calculation method was verified by analyzing the changes of carbon emission factors in typical days through practical examples.
Conclusion The research result suggests that more accurate, and the dynamic change of the factor can directly reflect the peak of carbon emission, encourage users to rationally plan their electricity consumption behavior and actively follow the carbon emission reduction policy.
