Marginal Carbon Emission Factors in Multiple Time Periods and Analysis of Their Uncertainties
The marginal carbon emission factor (MCEF) is an important index to reflect the influence of user load adjustment on carbon emission level of power system. The system operators can estimate and publish future MCEFs to guide consumers to use electricity in a low-carbon manner and reduce the total carbon emission. Aiming at the need of low-carbon guidance
the MCEF theory and its uncertainty considering the coupling of multiple time periods is studied. Firstly
from the economic dispatch model
the calculation method of MCEF considering the coupling of multiple time periods is derived theoretically
and the MCEF is decomposed into equilibrium component and blocking component by analogy with marginal electricity price. Then
based on multi-parametric linear programming theory
an adaptive fast calculation method for MCEF uncertainty analysis is proposed. Finally
case analysis based on IEEE 30-bus system is carried out to verify the effectiveness of the proposed method
and the key factors affecting the calculation results and uncertainties of MCEF are analyzed.
