本研究は、エネルギーシステムの多様性を評価するための分散調整済み多様性指標を提案し、EnergyPLANとOSeMOSYSを用いてデンマークとギリシャの100%再生可能エネルギー移行シナリオに適用した。化石燃料の段階的廃止は燃料多様性を低下させるが、地理的に分散した再生可能エネルギーの導入により全体の多様性指標は向上し、エネルギー安全保障とレジリエンスが強化されることを示した。
English
This study proposes a decentralization-adjusted diversity index to assess energy system diversity and applies it to 100% renewable energy scenarios for Denmark and Greece using EnergyPLAN and OSeMOSYS. It finds that while fossil fuel phase-out reduces fuel diversity, the deployment of geographically dispersed renewables increases overall diversity, enhancing energy security and resilience.

📄 Abstract（原文）
Energy systems are changing as a result of the transition to renewable energy from fossil fuels and the increased deployment and integration of fluctuating renewable energy sources. However, global supply chain challenges, energy crises, and geopolitical conflicts have underlined the need for not only reducing carbon emissions and optimising costs in energy systems but also ensuring energy security and resilience. This adds new dimensions to energy system modelling and to the evaluation of energy system scenarios as an integral part of energy strategy and energy policy development. This study reviews existing energy security and resilience indicators and proposes a decentralisation adjusted diversity index approach for assessing the diversity of energy systems. The proposed diversity index method can be applied alongside different energy system modelling frameworks and can be applied ex post to modelling outputs, as demonstrated by its use with EnergyPLAN and OSeMOSYS for two different national cases, Denmark and Greece. Both cases highlight energy systems transitioning from fossil fuel-based energy systems towards 100% renewable energy systems. Hence the study uses the decentralisation adjusted diversity index to evaluate how the dynamics of energy system diversity changes with the transition to variable renewable energy resources. The phase-out of fossil fuels reduces traditional energy fuel type diversity; however, this is offset by the implementation of geographically dispersed renewable energy sources. This results in an overall increased energy diversity index value for renewable energy systems and thereby increased energy system security and resilience.
