本論文は、変動性再生可能エネルギーの統合に必要な電力系統の柔軟性を評価する多地域最適化フレームワークを提案する。フランス南部4地域を対象に2023年のデータを用いた分析では、残差負荷は主に原子力ベースロードと地域間融通で満たされ、地域間融通が主要な柔軟性源となり、約9.1億ユーロの混雑収入を生み出すことを示した。感度分析により結果の頑健性を確認し、中間地域レベルの運用調整が技術的・経済的に有益であると結論付けた。
English
This paper proposes a multi-regional optimization framework to assess power system flexibility for integrating variable renewable energy. Applied to four southern French regions for 2023, it finds residual load is met by low-carbon dispatchable generation, mainly nuclear, and inter-regional exchanges are the primary flexibility source, generating significant congestion rents (~€0.91 billion). Sensitivity analysis confirms robustness, suggesting an intermediate regional layer for flexibility coordination is technically and economically beneficial.

📄 Abstract（原文）
In the context of the ongoing Energy Transition (ET), power system flexibility has emerged as a critical requirement for integrating increasing shares of Variable Renewable Energies (VREs) into electricity mixes. Because these resources are inherently location-specific, their large-scale deployment calls for a rethinking of how the balance between supply and demand is achieved. In this paper, we propose a multi-regional optimization framework to balance residual load using existing flexibility tools, including dispatchable generation, storage, demand response (DR), and inter-regional exchanges. Applying this framework to a cluster of four southern French regions for the full year 2023, we find that the residual load is met by an overwhelmingly low-carbon dispatchable mix dominated by nuclear baseload, and that inter-regional exchanges constitute the primary flexibility channel and generate substantial economic value through congestion rents ( ∼ 0.91 billion euros). We confirm the robustness of these findings through a dedicated sensitivity analysis spanning the hydro energy budget and the load recovery parameter. These results suggest that introducing an intermediate regional layer for the operation and coordination of power system flexibility could be beneficial from both a technical and an economic perspective.
