本論文は、UPFC（統合電力潮流制御装置）を用いた予防的最適潮流計算において、送電状態に依存する炭素取引決済手法を提案する。提案手法は、UPFCによる潮流制御とネットワーク損失を考慮し、発電側の利益を維持しつつ、線路損失と炭素排出をそれぞれ21.55%、7.13%削減することを実証した。炭素取引決済が発電後会計ではなく、送電状態と連動することを示した点が新規性である。
English
This paper proposes a transmission-state-dependent carbon-trading settlement method for UPFC-assisted preventive optimal power flow. Using Taiwan's 345 kV system, it demonstrates reductions in line losses (21.55%) and carbon emissions (7.13%) while maintaining generator profit. The key novelty is that carbon trading settlement is linked to transmission losses and thermal generation, not a post-dispatch accounting item.

日本のGX文脈において
日本ではカーボンプライシングの導入が進む中、FACTS機器（UPFC等）による系統制御と炭素取引を統合する本手法は、電力会社の送電運用とカーボンコスト管理に示唆を与える。特に、送電ロス低減と排出削減の両立が求められる日本において、実用的な枠組みとなりうる。
In the global GX context
As global carbon trading expands, this paper bridges the gap between transmission-level power flow control and carbon accounting. It offers a practical method for utilities to integrate carbon costs into operational dispatch, aligning with TCFD-aligned transition planning and ISSB's Scope 2 reporting.

📄 Abstract（原文）
Low-carbon OPF studies usually include carbon cost or emission limits in generation-side dispatch, while carbon-accounting studies often evaluate emissions after dispatch. The link between transmission-side flow control and carbon settlement has received less attention. In particular, it remains unclear how UPFC-driven changes in branch flows and losses should affect allowance balance, trading volume, and settlement cost in preventive OPF. This paper therefore proposes a transmission-state-dependent carbon-trading settlement method for UPFC-assisted preventive OPF. Different from post-dispatch carbon accounting, the proposed method calculates carbon-trading quantities from the same network-feasible dispatch solution that determines UPFC-regulated flows, network losses, thermal generation, and contingency feasibility. The model is written in equivalent current injection form. A social-learning artificial bee colony algorithm with feasibility repair is used to solve the constrained problem, with infeasible trial solutions repaired according to power-balance, operating-limit, and carbon-trading constraints. The Taipower 345 kV transmission system is used for testing. Under the annual average daily load condition, line losses are reduced from 27,126.55 MWh to 21,281.92 MWh, while carbon emissions decrease from 300,988.72 tCO2 to 279,527.70 tCO2, corresponding to reductions of 21.55% and 7.13%. The generator-side profit remains positive at TWD 11,000,763. The combined UPFC-PCOPF case also satisfies the screened post-contingency line-loading and voltage constraints. The full-year cases show a similar reduction pattern. These results suggest that carbon-trading settlement is not a fixed post-dispatch accounting item. In UPFC-assisted dispatch, it is linked to transmission losses and thermal generation.
