English
This study proposes a multi-objective capacity optimization method for PV-storage systems in low-carbon buildings, leveraging the flexibility of orderly EV charging. A bi-level model is developed: the upper level minimizes the operator's economic and carbon costs while optimizing capacity and charging prices; the lower level minimizes EV users' charging costs. Case results show reduced building costs and electricity-related carbon emissions, demonstrating the value of incorporating carbon into demand-side optimization.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では再エネ導入拡大とEV普及が進む中、需要側の柔軟性を活用した容量設計は、ZEBやカーボンニュートラル建築の実務に直結する。SSBJや有報でのScope 2・3開示を進める企業にとって、建物単位の炭素コスト最適化は投資判断の参考になる。
In the global GX context
Globally, this contributes to the growing literature on demand-side flexibility and building decarbonization, relevant to TCFD/ISSB disclosure of Scope 2 and 3 emissions. It offers a quantitative framework for integrating carbon costs into capacity planning, useful for corporate net-zero strategies and smart city pilots.

📄 Abstract(原文)
To support low-carbon smart buildings, this study proposes a multi-objective capacity optimization method for PV-energy storage systems considering the flexibility potential of orderly electric vehicle (EV) charging loads. First, an orderly EV charging model based on price-guided charging quantifies the flexibility potential of EV charging loads. Then, a bi-level multi-objective capacity configuration model is proposed. In the upper level, the building operator minimizes both economic and carbon emission costs, jointly optimizing PV-energy storage capacity configuration and EV charging prices. In the lower level, EV users optimize their charging schedules to minimize their charging costs in response to the charging prices. To solve this bi-level multi-objective problem, the two objectives are normalized and weighted into a single-objective function, and then a heuristic solution method based on a genetic algorithm is developed. Case study results show that the proposed mode reduces building economic cost and electricity-related carbon emissions, demonstrating the benefits of incorporating carbon emissions into demand-side optimization under the “dual-carbon” targets.
