本論文は、ポルトガルにおける第三者運営のエネルギーコミュニティ（EC）ビジネスモデルの経済的実現可能性を分析する。中央集約型アグリゲーターが太陽光発電、蓄電池、需要側柔軟性資産を所有・運用し、集合自己消費（CSC）とピアツーピア（P2P）取引を比較。最適パラメータ（17%の共有割引、入札調整なし）を特定し、CSCがコミュニティのエネルギーコストを5.3%削減し、アグリゲーターに年12%の収益をもたらすことを示した。また、30.9%の自給率と30.60%のCO2排出削減を達成。
English
This paper analyzes the economic viability of a third-party-operated energy community (EC) business model in Portugal, where a central aggregator owns and manages shared PV, battery storage, and demand-side flexibility assets. Comparing collective self-consumption (CSC) and peer-to-peer (P2P) trading, it identifies optimal parameters (17% sharing discount, no bid adjustment) and shows CSC reduces community energy costs by 5.3%, yields a 12% annual return for the aggregator, and achieves 30.9% self-sufficiency and 30.60% CO2 emission reduction.

📄 Abstract（原文）
The transition to decentralized, low-carbon energy systems has positioned energy communities (ECs) as a key instrument for enhancing local energy autonomy, promoting citizen participation, and integrating renewable generation. This paper examines the economic viability of a Portuguese third-party-operated energy community business model in which a central aggregator-retailer owns and manages shared photovoltaic, battery storage, and demand-side flexibility assets. The study compares collective self-consumption (CSC) and peer-to-peer (P2P) trading under a centralized multi-objective optimization framework, assessing how pricing rules affect community savings and aggregator profitability. A sensitivity analysis identifies a 17% sharing discount and no bid adjustment as optimal parameters for CSC and P2P models, respectively. The CSC configuration proves more effective in balancing community savings and aggregator profitability, achieving a 5.3% reduction in community energy costs and a 12% annual return for the aggregator, along with 30.9% self-sufficiency and 30.60% CO 2 emissions reduction. In contrast, P2P models favor the community side, offering higher savings but limiting the aggregator's revenue. Pareto frontier analysis confirms that CSC is the most robust model under centralized assets ownership in the current assumptions. A successful implementation will always depend on aligning the objectives of third-party entities and participants within a balanced business model that ensures fairness and economic viability under the applicable regulatory constraints.
