高速道路サービスエリアを多エネルギー拠点と捉え、段階的炭素取引メカニズム下での電気・水素・熱統合エネルギーシステムの日前運用最適化モデル（MILP）を構築。廃熱放棄の柔軟性を導入することで運用コストを6.63%削減できる一方、炭素排出が4.05%増加するリバウンド現象を発見。炭素価格の探索により、排出削減とコスト削減を両立する遷移点を特定した。
English
This study develops a day-ahead MILP model for an electricity-hydrogen-heat integrated energy system in a highway service area under a stepped carbon trading mechanism. Introducing waste-heat-rejection flexibility reduces operating cost by 6.63% but increases carbon emissions by 4.05%, revealing a rebound effect. A refined carbon-price search identifies a transition point where both cost and emission reductions can be achieved, offering insights for carbon pricing design.

📄 Abstract（原文）
As highway service areas evolve into multi-energy hubs, the interaction between physical operating flexibility and carbon-price incentives becomes increasingly important. This study develops a day-ahead mixed-integer linear programming (MILP) framework for an electricity–hydrogen–heat integrated energy system in a highway service area under a stepped carbon trading mechanism. An explicit waste-heat-rejection channel is introduced to relax the fuel-cell heat–power coupling constraint. Within the adopted microgrid dispatch accounting boundary, the autonomous hydrogen production–storage–utilization chain reduces the microgrid dispatch operating cost by 5.36%. Under the benchmark parameter settings, enabling waste-heat-rejection flexibility shifts fuel-cell generation toward peak-price periods and reduces operating cost by 6.63%, but increases actual carbon emissions from 1314.47 to 1367.67 kgCO 2 e, corresponding to a 4.05% carbon emission rebound. A refined carbon-price search localizes the dispatch transition to 8 . 3 6 5 4 < 𝑁 𝑡 𝑟 𝑎 𝑛 𝑠 𝑖 𝑡 𝑖 𝑜 𝑛 ≤ 8 . 3 6 5 5 (approximately 𝑁 = 8 . 3 7 ), corresponding to a first-stage benchmark carbon price of approximately 0.669 CNY/kgCO2e and an active third-stage marginal carbon price of approximately 2.008 CNY/kgCO 2 e. Scenario-based uncertainty and extended sensitivity analyses further show that the rebound is not universal and may disappear or be replaced by simultaneous cost and emission reductions under different source–load conditions, hydrogen demand, and conversion-performance parameters.
