本研究は、電力系統プロジェクト(PGP)を11の標準モジュールに分解し、改良PSO-DRESNモデルを用いてモジュール別の炭素クォータを高精度に決定する枠組みを提案。500kV PGPのライフサイクル排出量は13,569.1 tCO2eで、運用保守段階が54.4%を占める。高容量導体や低損失変圧器が最も炭素弾力的な介入策と特定され、断片的なエンジニアリングデータを標準化されたモジュールクォータに変換することで、系統管理者にライフサイクルベースの炭素ベンチマークと脱炭素戦略最適化のための科学的ツールを提供する。
English
This study proposes a framework that decomposes power grid projects into 11 standard modules and uses an improved PSO-DRESN model to determine modular carbon quotas with high precision. Empirical analysis of a 500kV PGP reveals a lifecycle footprint of 13,569.1 tCO2e, with O&M as the dominant phase (54.4%). High-capacity conductors and low-loss transformers are identified as the most carbon-elastic interventions, transforming fragmented engineering data into standardized modular quotas for utility managers to set lifecycle carbon benchmarks and optimize decarbonization strategies.

日本のGX文脈において
本論文は、系統プロジェクトの炭素排出量をモジュール単位で精緻に評価する手法を提供し、日本の電力事業者がSSBJ対応やGHG排出量の見える化を進める上で参考になる。特に、運用段階が排出の過半を占める点は、日本の既存インフラの長寿命化・効率化を検討する際に重要である。
In the global GX context
This paper presents a modular lifecycle accounting framework for power grid projects, relevant to global TCFD/ISSB-aligned carbon disclosure and transition finance. The finding that O&M phase dominates emissions highlights the need for asset management strategies that extend beyond construction, offering a benchmark for utilities worldwide to identify carbon-elastic retrofit measures.

📄 Abstract（原文）
Power Grid Projects (PGPs) are pivotal to energy transition, yet their complex engineering structures hinder precise carbon quantification. This study proposes a modular carbon emission accounting and evaluation framework for different types of PGPs. By deconstructing projects into 11 typical modules, we establish a modular-lifecycle that aligns physical engineering logic with carbon characteristic extraction. The research develops an automated method-matching engine and utilizes an Improved Particle Swarm Optimization-Deep Reservoir Echo State Network (IPSO-DRESN) model to determine modular carbon quotas with high precision. Empirical analysis reveals that the total lifecycle footprint of 500kV PGP is 13,569.1 tCO2e. The Operation and Maintenance (O&M) phase is the dominant emission source (54.4%), while the Production and Construction (P&C) phase (38.2%) is characterized by intense mechanical energy consumption. This research further establishes a low-carbon retrofit evaluation system, identifying high-capacity conductors and low-loss transformers as the most “carbon-elastic” interventions. By transforming fragmented engineering data into standardized modular quotas, this study provides a rigorous scientific tool for utility managers to implement lifecycle-based carbon benchmarks and optimize decarbonization strategies in the power sector.
