本論文は、省間電力スポット取引を考慮した省別平均炭素排出係数のリアルタイム計算手法を提案する。損失のある電力網を損失のないものに等価化し、取引電力と非取引電力に分離して炭素排出量を計算する。ケーススタディにより手法の有効性を検証。高比率の再生可能エネルギー導入下での排出係数のリアルタイム変動に対応。
English
This paper proposes a real-time calculation method for provincial average carbon emission factors that accounts for inter-provincial electricity spot trading. It equivalently converts lossy power networks to lossless ones, separates traded and non-traded electricity, and uses average emission factor and carbon emission flow theory. A case study validates the method, addressing real-time fluctuations under high renewable penetration.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の電力システムでも、地域間連系線を通じたスポット取引が進んでおり、本手法はScope 2排出量の精度向上に寄与する可能性がある。特に、再生可能エネルギーの比率上昇に伴う排出係数の変動をリアルタイムで捉える点は、日本企業のカーボンアカウンティング実務に示唆を与える。
In the global GX context
This method is globally relevant as many countries with interconnected grids and spot markets (e.g., EU, US, China) face similar challenges in accurately calculating emission factors. It improves the precision of Scope 2 accounting and supports carbon market integrity, especially with growing renewable energy shares.
👥 読者別の含意
🔬研究者:Researchers in carbon accounting and power system modeling can adopt this real-time emission factor methodology for grids with high renewables and cross-border trading.
🏢実務担当者:Corporate sustainability teams can use this method to more accurately calculate Scope 2 emissions from purchased electricity, especially when sourcing from multiple regions via spot markets.
🏛政策担当者:Regulators designing carbon accounting rules or carbon markets can consider this approach to improve emission factor granularity and reflect real-time grid conditions.
📄 Abstract（原文）
The calculation method for carbon emission factor in electricity systems is a critical foundation for accurately quantifying carbon emissions from electricity. This study addresses the limitations of the average carbon emission factor method, which struggle to adapt to the real-time fluctuations in carbon emission intensity under high proportions of renewable energy integration and fail to account for the transfer of green electricity environmental attributes caused by inter-provincial spot trading. Therefore, this paper proposes a real-time calculation method of average carbon emission factor for provincial electricity which considers inter-provincial electricity spot trading. Firstly, the lossy electricity network is equivalent to the lossless electricity network; Secondly, according to the inter-provincial spot traded rules, the electricity flow is divided into traded electricity and non-traded electricity; Thirdly, the average carbon emission factor method and carbon emission flow theory are used to calculate the carbon emissions of the two parts of electricity, and finally, the carbon emissions of the two parts of electricity are integrated to calculate the carbon emission factor of electricity after considering spot trading. The case study validates the applicability and effectiveness of this method.
