随着气候变化在21世纪站稳脚跟，它推动了美国电力系统的可再生能源脱碳。本文介绍了美国电力系统的结构弹性分析，逐步纳入架构的变化，包括网状配电线路，分布式发电，储能解决方案。异功能图分析证实了我们从网络科学的累积度分布和传统的攻击脆弱性措施的正式图形的理解。此外，本文还表明，异功能图更精确地描述了与分布式发电和储能相关的功能变化。最后，它表明，增加所有三种类型的缓解措施，提高电网的结构弹性，即使在破坏性攻击的存在。本文的结论是，电网的可持续性和弹性之间没有结构性的权衡。
As climate change takes hold in the 21st century, it places an impetus to decarbonize the American electric power system with renewable energy resources. This paper presents a structural resilience analysis of the American electric power system that incrementally incorporates architectural changes including meshed distribution lines, distributed generation, and energy storage solutions. A hetero-functional graph analysis confirms our formal graph understandings from network science in terms of cumulative degree distributions and traditional attack vulnerability measures. Additionally, The paper shows that hetero-functional graphs more precisely describe the changes in functionality associated with the addition of distributed generation and energy storage. Finally, it demonstrates that the addition of all three types of mitigation measures enhance the grid's structural resilience; even in the presence of disruptive attacks. The paper concludes that there is no structural trade-off between grid sustainability and resilience.
