発電・系統・負荷・蓄電を一体運用する際、電力価格ではなく時間変動する炭素排出責任係数（CERF）を低炭素誘導信号として用いる協調運用枠組みを提案。事前運用で基準スケジュールを算出しCERFを導出、再運用段階でV2Gと柔軟資源を連携させる多目的最適化を構築。炭素・グリーン証書取引も組み込み、ベンチマーク比で運用コスト3.87%、炭素排出13.78%、ピーク・ボトム差58.50%を削減した。

English

This study proposes a low-carbon coordinated dispatch framework for source–grid–load–storage systems that uses a time-varying carbon emission responsibility factor (CERF) as a guidance signal instead of electricity prices. A pre-dispatch stage sets baseline schedules and derives the CERF, while a re-dispatch stage coordinates V2G and flexible resources via multi-objective optimization with carbon and green certificate trading. Compared with the benchmark, costs, emissions, and peak-to-valley load difference fall by 3.87%, 13.78%, and 58.50% respectively.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

炭素責任を時間軸で可視化し需要側の柔軟性（EV・V2G）を動かす発想は、日本での需給調整市場や非化石証書・容量市場と組み合わせた低炭素運用設計に示唆を与える。SSBJ開示でScope2の時間別排出係数管理が論点となる日本企業にも参考になる。

In the global GX context

The paper operationalizes time-varying carbon responsibility as a dispatch signal, aligning with global moves toward hourly/nodal carbon accounting and market-based Scope 2 (GHG Protocol, CSRD/ESRS E1). It adds empirical evidence that V2G flexibility can be monetized for decarbonization, relevant to transition-finance and grid-flexibility debates.

📄 Abstract（原文）

Abstract Conventional coordinated dispatch of source–grid–load–storage systems is largely driven by electricity prices, limiting its ability to reflect time-varying carbon responsibility in electricity consumption and to fully utilize the low-carbon flexibility of resources such as electric vehicles. To address these limitations, this study develops a low-carbon coordinated dispatch framework for a source–grid–load–storage system by integrating the carbon emission responsibility factor (CERF) with vehicle-to-grid (V2G) interaction. In the pre-dispatch stage, system operating costs are minimized to determine baseline schedules for individual system components, from which the time-varying CERF is calculated. In the re-dispatch stage, the CERF is used as a low-carbon guidance signal to coordinate V2G participation and other flexible resources. A multi-objective optimization model incorporating carbon and green certificate trading mechanisms is then formulated to balance system economic performance and load regulation capability. Scenario comparisons show that the CERF guides flexible electricity consumption toward periods with lower carbon responsibility, while V2G provides the bidirectional charging and discharging flexibility required for low-carbon dispatch. Compared with the benchmark scenario, the coordinated application of the CERF and V2G reduces total system operating costs, carbon emissions, and the peak-to-valley load difference by 3.87%, 13.78%, and 58.50%, respectively. These results indicate that combining carbon-responsibility-based guidance with V2G flexibility can achieve a coordinated balance among economic performance, low-carbon operation, and load regulation.
