本論文は、アグリゲータが内部売買価格を設定し、各コミュニティ構成員が太陽光・蓄電池・需要応答を独立最適化する二段階（Stackelbergゲーム）最適化枠組みを提案する。上位問題を進化アルゴリズム、下位問題を線形・混合整数計画で解き、価格信号と需給スケジュールのみを交換することでプライバシーを保ちつつ集中型に近い経済性を達成する。均質・異質な構成での評価により、非協調運用より総運用コストを大幅に削減できることを示す。
English
This paper proposes a bi-level Stackelberg optimization framework for energy community operation, where an aggregator sets internal prices and members independently optimize PV, battery storage, and flexible demand. The upper level uses an evolutionary algorithm and lower levels are solved via LP/MILP, preserving privacy by exchanging only price signals and import/export schedules. Results show near-centralized economic performance and significant cost savings versus uncoordinated operation, with adaptable objectives to redistribute benefits.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では地域新電力やエネルギーマネジメント、需給調整市場との連携が進む中、アグリゲータ主導の価格設計とプライバシー配慮型運用は、地域脱炭素・分散型電源活用の実務設計に示唆を与える。SSBJ開示とは直接結びつかないが、再エネ導入とコスト最適化の根拠として参照価値がある。
In the global GX context
As energy communities and aggregator models scale under EU renewable and flexibility frameworks, this work offers a privacy-preserving, computationally tractable alternative to centralized coordination, relevant to transition-finance-backed distributed energy business models and to disclosure of community-level decarbonization performance.

📄 Abstract（原文）
Energy communities are expected to play a key role in the energy transition by supporting the deployment of renewable energy technologies. Their full potential can be unlocked through coordinated operation, typically managed by an aggregator. However, centralized approaches raise concerns regarding privacy, computational scalability, and the conflicting objectives of the community participants. To address these challenges, this work proposes a bi-level optimization framework for the operational management of energy communities. The formulation is based on a single-leader, multiple-followers Stackelberg game, in which the aggregator determines the internal electricity purchase and selling prices, while the community members independently optimize the operation of their local energy systems, including photovoltaic generation, battery energy storage, and flexible demand. The upper-level problem is solved using an evolutionary algorithm tailored for non-smooth problems, while the lower-level problems are solved to optimality using linear or mixed-integer linear programming. The framework supports both centralized and distributed implementations, preserving prosumer privacy by exchanging only price signals and electricity import/export schedules. The proposed approach is evaluated on several homogeneous and heterogeneous energy community configurations with realistic load profiles. The results show that the proposed framework achieves economic performance close to that of a centralized benchmark while significantly reducing the total operating cost compared with uncoordinated operation. Furthermore, it is demonstrated that the upper-level objective function can be adapted to improve the distribution of economic benefits among community members, highlighting the flexibility of the proposed optimization framework.
