本研究は、変動料金制における住宅用屋上太陽光発電（PV）の財務リスクを軽減するため、不確実性を考慮したスマートバッテリー管理手法を提案する。ドイツ・ゲルゼンキルヒェンの事例分析により、提案手法は従来の確定的戦略と比較して、高価格露出指数を31.94%から1.97%に低減し、バッテリーのコスト削減利用率を100%に向上させることを実証した。
English
This study proposes a simulation-based smart battery management strategy that incorporates uncertainty modeling to mitigate financial risk for residential rooftop PV systems under dynamic electricity tariffs. A case study in Gelsenkirchen, Germany, demonstrates that the uncertainty-aware strategy reduces the High Price Exposure Index from 31.94% to 1.97% and increases Battery Utilization for Cost Reduction to 100%, outperforming deterministic baselines.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本論文は、変動料金下での住宅用太陽光発電の財務リスク管理に焦点を当てており、日本でもFIP制度導入や時間帯別料金の拡大に伴い、プロシューマーの収益安定化策として示唆に富む。ドイツの事例ではあるが、不確実性を考慮したバッテリー運用は、日本の需給調整市場や自家消費最適化にも応用可能である。
In the global GX context
This paper provides a practical approach to enhancing financial resilience of residential PV systems under dynamic pricing, a common feature of evolving electricity markets in the global energy transition. While the case study is in Germany, the methodology is transferable to other regions implementing time-varying tariffs or net billing schemes.

📄 Abstract（原文）
Rooftop photovoltaic (RPV) systems play a key role in reducing carbon emissions and increasing distributed electricity generation. However, under dynamic electricity tariffs, conventional deterministic battery management strategies often fail to account for the stochastic nature of photovoltaic (PV) generation and household electricity demand, leading to increased financial risk and suboptimal economic performance. This study proposes a simulation-based smart battery management strategy that explicitly incorporates uncertainty modeling to mitigate financial risk under dynamic pricing schemes. Seasonal and intraday probability distributions are fitted to historical PV generation and consumption data, enabling a stochastic representation of supply-demand variability. Battery dispatch decisions are evaluated under dynamic tariffs with a focus on financial risk exposure rather than average cost minimization alone.A case study of a four-person household in Gelsenkirchen, Germany, demonstrates that the proposed uncertainty-aware strategy significantly enhances financial resilience. Compared to a price-blind baseline strategy, the High Price Exposure Index (HPEI) is reduced from 31.94% to 1.97%, while Battery Utilization for Cost Reduction (BUCR) increases from $\mathbf{4 8. 9 0 \%}$ to 100%. These findings demonstrate that uncertainty-aware battery control enables robust financial protection by systematically reallocating storage usage toward high-risk price periods, rather than relying on deterministic average-based strategies.
