本論文は、炭素排出フロー（CEF）とノード炭素強度（NCI）を組み込んだユーザー中心の低炭素ディスパッチ枠組みを提案。需要応答（DR）と物理的な電力供給制約を考慮し、対象ユーザーのスコープ2排出量を最小化する。IEEE 14母線系統でのケーススタディにより、ノードの脱炭素効果は系統トポロジーに依存し、CEF-DR戦略が単一メカニズムより優れることを示した。
English
This paper proposes a user-centric low-carbon dispatch framework integrating carbon emission flow (CEF), nodal carbon intensity (NCI), network constraints, and demand response (DR). It minimizes the target user's physically traced Scope 2 emissions under a cost budget and flexible load. Case studies on a modified IEEE 14-bus system show that nodal decarbonization is topology-dependent and that the CEF-DR strategy outperforms single mechanisms.

📄 Abstract（原文）
Sustainable power-system operation requires carbon-reduction strategies that are emission-effective, physically deliverable, economically feasible, and compatible with user-side decarbonization claims. As Scope 2 carbon accounting increasingly emphasizes temporal, spatial, and physical consistency, dispatch models need to link user-level carbon claims with network-constrained power delivery. This paper proposes a User-Centric Carbon Cost-Constrained Low-Carbon Dispatch (CCC-LCD) framework that integrates carbon emission flow (CEF), nodal carbon intensity (NCI), network-constrained optimal dispatch, and endogenous demand response. A PTDF-based DC-OPF model represents active-power deliverability, while dual virtual flow variables determine carbon-flow directions endogenously. The model minimizes the target user’s physically traced Scope 2 emissions under a cost-tolerance budget and flexible-load constraints. Case studies on a modified IEEE 14-bus system show that nodal decarbonization is topology-dependent: high-load and high-NCI nodes obtain larger reductions from source-side generation substitution, whereas renewable-adjacent nodes exhibit limited marginal gains. The CEF-DR strategy outperforms single-mechanism cases, indicating the value of coordinating physical carbon-flow constraints with flexible demand. From a sustainability perspective, the proposed framework supports verifiable low-carbon electricity consumption, improves the economic feasibility of user-side decarbonization, and provides a practical dispatch tool for sustainable energy transition and corporate Scope 2 emission reduction.
