Description

Technical Field

[0001] This invention relates to the field of carbon metering technology, and more specifically, to a method for calculating user-side carbon emissions adapted to electricity trading scenarios. Background Technology

[0002] The power system is a major source of carbon emissions from electricity in my country, accounting for over 40% of total carbon emissions from fossil fuel combustion. Therefore, measuring carbon emissions from electricity consumption in the electricity market is a prerequisite for quota setting and a crucial basis for trading. Electricity carbon metering technology is the technological foundation for ensuring accurate and reliable measurement results. The power system generates actual carbon emissions on the generation side, which are attached to the generated electricity and transmitted to users through the transmission and distribution network. In other words, users generate indirect carbon emissions simultaneously with their electricity consumption. Previously, scholars proposed the carbon emission flow method, which, based on detailed analysis of defined parameters such as carbon flow rate, carbon flow density, and carbon potential, theoretically calculates user-side carbon emissions and calculates the indirect carbon emissions at each stage using the power system flow matrix. However, these methods do not consider the impact of electricity market transactions on carbon emissions.

[0050] ③ Decoupling of traded and non-traded electricity.

W 用电 Non-transactional electricity used by users.

[0054] ⑤ Obtain the carbon emissions of trading users and non-trading users. For non-trading users, their carbon emissions are the result of equation (6); for trading users, the result of equation (6) is their non-trading carbon emissions. The total carbon emissions also need to be added to the result of equation (2), that is, the carbon emissions of trading users are: (7) Therefore, this invention can be used to provide users participating in the electricity market with calculations of indirect electricity carbon emissions, and in conjunction with distributed electricity carbon metering devices and systems, to realize real-time updates of indirect electricity carbon emissions on the user side, providing time-sensitive carbon trading certificates.
