摘要

Abstract

Accurately quantifying the carbon emission reduction (CER) of renewable energy (RE) is crucial for the coupled electricity-carbon market. However

traditional methods based on regional average emission factors ignore topological constraints and transmission losses causing systematic biases in evaluating RE's environmental value. To address this

this paper proposes a high-precision physics-based CER accounting framework integrating topological sensitivity mapping with bidirectional network loss allocation. First

an improved generation shift distribution factor (GSDF)-based marginal emission factor model is established to overcome geographical blindness and precisely identify specific high-carbon marginal units displaced by RE. Second

upstream and downstream power flow tracing algorithms are utilised to bidirectionally allocate network losses

equitably attributing carbon emissions embedded in dissipated energy. Third

a virtual lossless network is reconstructed and RE is treated as a negative virtual load

through which the precise displacement pathways from marginal units to RE nodes are rigorously mapped. Case studies on a regional power grid in Zhejiang

China

demonstrate that the proposed framework successfully corrects systematic underestimations providing a highly credible pricing benchmark for green certificates and carbon assets.
