Description

Technical Field

[0001] This invention relates to the field of data processing and analysis technology for energy and power systems, and in particular to a method and system for calculating the average carbon footprint factor of a regional power system throughout its entire life cycle. Background Technology

[0002] Regional power systems account for a significant proportion of the nation's total carbon emissions, and power cables are ubiquitous within these systems, generating carbon emissions during their production, transportation, use, and disposal. Therefore, ensuring accurate calculation of the carbon footprint of power cables is of paramount importance.

[0003] Generally, there are three main methods for calculating carbon footprint: emission factor method, mass balance method, and measurement method. Emission factor method: simple and fast, suitable for indirect emissions (such as purchased electricity) and preliminary estimates, relying on industry average data. Mass balance method: the preferred method for industrial processes, tracking carbon flows (such as chemicals and steel), requiring detailed material data, and offering high accuracy. Measurement method: precisely monitoring stationary sources (such as chimneys), high cost, used for regulatory compliance (such as carbon trading).

[0004] However, when processing multi-source data (such as supply chain activity data and background database emission factors), traditional methods struggle to dynamically integrate the temporal, geographical, and technological differences in data representativeness, and fail to consider the weighting effect of carbon footprint contribution rates, easily leading to the neglect of data quality biases in high-emission segments. In calculating regional carbon footprints, the spatiotemporal distribution of distribution network carbon footprints is even more complex, posing new challenges to carbon footprint analysis and rendering traditional methods for accurate carbon emission flow calculation unsuitable for practical analysis of distribution network carbon footprints.
