鉴于现有电力系统中高冲击低概率(HILP)事故的发生越来越多，加强这些系统的弹性变得至关重要。提高电力系统的复原力不仅是一个技术问题，也是一个社会经济和政策问题。因此，提高电力系统的性能在很大程度上依赖于能源政策的指导。虽然这些缓解气候变化的政策支持的脱碳反应影响了能源技术的采用，但它对系统复原力的影响仍然不确定。为了揭示与电力系统弹性有关的技术、政策和经济之间的相互作用，本研究致力于构建面向弹性的网络化微电网系统。在考虑排放政策的情况下，通过整合一种选择用户确定的停电情景的方法，建立了一个两阶段随机规划模型。结果证实了综合系统在增强复原力方面的贡献，但它们也表明，低碳排放政策通过增加与复原力规划和运作相关的财务成本而发挥抑制作用。尽管如此，综合网络仍然可以实现30%的减排门槛，从而实现最大限度地减少排放和最大限度地减少排放税负担的双重好处。这项研究的贡献有三个方面：第一，它同时纳入了技术-经济激励措施和法规；第二，它量化了政策对复原力的意外后果；第三，它为未来的能源政策制定提供了建设性的指导，特别是在维持系统复原力方面。
Given the increasing occurrence of high-impact low-probability (HILP) contingencies in existing power systems, strengthening the resilience of these systems has become of paramount importance. Enhancing the resilience of power systems is not solely a technical issue but also a socio-economic and policy concern. Therefore, improving the performance of power systems greatly relies on the guidance provided by energy policies. While the decarbonization response, supported by these policies to mitigate climate change, influences the adoption of energy technologies, its impact on the resilience of the system remains uncertain. To uncover the interactions between technologies, policies, and economics concerning power systems resilience, this study focuses on constructing resilience-oriented networked microgrid systems. It develops a two-stage stochastic programming model by integrating a method for selecting power outage scenarios identified by users, in the presence of emissions policies. The results confirm the contributions of integrated systems in enhancing resilience, but they also reveal that low-carbon emissions policies play an inhibiting role by increasing the financial costs associated with resilience planning and operations. Nevertheless, a 30% emissions reduction threshold can still be achieved from the integrated network, facilitating the dual benefits of maximizing emissions reduction and minimizing the burden of emissions taxes. The study's contributions are threefold: firstly, it incorporates techno-economic incentives and regulations simultaneously; secondly, it quantifies the unintended consequences of policies on resilience; and thirdly, it provides constructive guidance for future energy policymaking, particularly in maintaining system resilience.
