本論文は、ニュージーランドのワイヘキ島を対象に、需要側柔軟性を活用した配電網の投資延期とコミュニティ便益の可能性を評価したデータ駆動型ケーススタディである。家庭の給湯器、EV充電、屋上太陽光、家庭用・コミュニティ用バッテリーを調整する需要応答管理フレームワークを開発し、実際のスマートメーターデータを用いて島全体のシミュレーションを実施。結果、夕方のピーク需要を大幅に削減し、配電網の増強を遅らせ、経済的便益を生み出すことを示した。
English
This paper presents a data-driven case study of Waiheke Island, New Zealand, evaluating demand-side flexibility for deferring distribution network investments and generating community benefits. A demand response management framework coordinates household hot-water cylinders, EV charging, rooftop solar, and battery storage. Using real smart-meter data and island-wide simulations, the study shows that rescheduling flexible loads can substantially reduce evening peak demand, delay network reinforcement, and yield significant economic benefits.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では再生可能エネルギーの導入拡大に伴い配電網の混雑が課題となっており、需要側柔軟性は非ネットワーク対策として注目される。本ケーススタディは、SSBJや有報での情報開示が進む中、系統投資の回避がもたらす経済的価値を定量的に示す点で、日本の電力会社や地域コミュニティの計画立案に示唆を与える。
In the global GX context
Globally, as distributed energy resources grow, distribution networks face congestion and costly upgrades. This study provides empirical evidence that demand-side flexibility can defer network investments, aligning with TCFD/ISSB disclosure themes on climate resilience and transition planning. It offers a replicable methodology for utilities and regulators to assess non-wire alternatives.

📄 Abstract（原文）
The decarbonisation of the energy system is accelerating the uptake of distributed and renewable energy resources. Nevertheless, this stresses already-constrained distribution networks, and it can lead to expensive grid infrastructure upgrades. Demand-side flexibility offers a non-network solution that can reduce power grid reinvestment and reinforcement. This paper investigates the potential of demand-side flexibility, where we explore community energy sharing and coordinated demand response through a data-driven case study for Waiheke Island, New Zealand. In particular, a demand response management framework is developed that coordinates household hot-water cylinders, EV charging, rooftop solar power, and home and community battery storage. The framework is first evaluated in a community-scale energy-sharing scenario that incorporates flexible load scheduling and market-level settlement. The analysis is then extended to the entire Waiheke Island under a realistic demand-response setting, supported by a digital representation of the island’s electricity network and energy system. The study integrates real household smart-meter data, feeder-level consumption data, and information obtained from multiple publicly available sources to assess the island-wide potential for demand-side flexibility. Detailed simulations show that rescheduling hot-water cylinder operation, EV charging, and household battery storage can substantially reduce the island’s evening peak demand, thereby delaying network reinforcement and generating significant economic benefits.
