日本語

本研究はカナダの遠隔オフグリッドコミュニティ向けにAC結合型ハイブリッドマイクログリッドを提案・評価した。Black Tickleを対象とした最適化構成では風力浸透率86.7%、100%の供給信頼性を達成したが、バッテリー貯蔵が年間コストの73.5%を占め経済的課題が明らかになった。感度分析によりディーゼル価格変動が炭素価格変更よりも約4.1倍大きな影響を与えることが示された。

English

This study proposes and evaluates an AC-coupled hybrid distribution microgrid for remote off-grid communities in Canada, using Black Tickle as a case. The optimized configuration achieves 86.7% wind penetration and 100% supply reliability, but battery storage accounts for 73.5% of annualized costs, a key economic challenge. Sensitivity analysis shows diesel price fluctuations have about 4.1 times greater influence on system economics than carbon pricing changes.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本でも離島や山間部の遠隔コミュニティはディーゼル依存が課題であり、本論文の技術経済分析は同様の状況における再生可能エネルギー導入の参考となる。ただし、カナダ特有の気候条件や補助金制度が日本にそのまま適用できるわけではない点に注意が必要。

In the global GX context

This paper contributes to the global understanding of microgrids as a decarbonization pathway for remote areas, highlighting the importance of diesel price volatility over carbon pricing. It offers a detailed techno-economic model that could be replicated in other remote communities, but the specific cost structure and climate conditions are Canada-specific.

👥 読者別の含意

🔬研究者:Provides a validated optimization model for AC-coupled wind-diesel-battery microgrids and sensitivity analysis demonstrating diesel price dominance over carbon pricing.

🏢実務担当者:Offers a replicable design framework for remote community microgrids, with clear cost breakdown and reliability metrics that can inform project planning.

🏛政策担当者:Emphasizes that carbon pricing alone may be insufficient to drive diesel displacement in remote communities; diesel price volatility is a stronger economic lever.

📄 Abstract（原文）

Remote communities in Canada face high electricity costs, energy insecurity, and significant greenhouse gas emissions due to heavy dependence on diesel generation. This study proposes and evaluates an AC-coupled hybrid distribution microgrid for remote off-grid communities, using Black Tickle, Newfoundland and Labrador as a representative case study. The system integrates two 200 kW wind turbines, a 200 kW diesel backup generator, a 16 MWh lithium-ion battery storage system, and a bidirectional converter, modeled and optimized in HOMER Pro 3.18.3 using local meteorological data, community load profiles, and a cycle-charging dispatch strategy. The optimized configuration achieves 86.7% wind penetration and 100% supply reliability with zero unmet load, yielding a total net present cost of USD 13.6 million and a levelized cost of energy of 0.999 USD/kWh over a 25-year horizon. Battery storage accounts for 73.5% of annualized costs, representing the primary economic challenge for wider deployment. Sensitivity analyses show that diesel price fluctuations exert approximately 4.1 times greater influence on system economics than equivalent carbon pricing changes, while the optimal configuration remains robust across all tested policy scenarios. These findings demonstrate that AC-coupled wind–diesel–battery microgrids offer a viable pathway for reducing fossil fuel dependence and supporting clean energy transition in remote, harsh-climate communities.
