微电网弹性:一个整体和上下文感知的弹性度量

Microgrid Resilience: A Holistic and Context-Aware Resilience Metric

Sakshi Mishra, Ted Kwasnik, Kate Anderson

摘要:

微电网为各种分布式能源的协调部署提供了有效的解决方案,并为能源消费者和整个能源系统提供了无数额外的好处,如弹性,减少碳足迹和可靠性。提高配电系统的弹性是微电网的另一个主要好处。这是因为它们还可以在公用电网运营因高概率低影响事件(如组件故障)或低概率高影响事件(无论是自然灾害还是有计划的网络攻击)而中断时作为备用电源。然而,任何特定系统可以防御、适应和恢复正常运行的程度取决于各种因素,包括微电网所遭受的事件的类型和严重程度。这些因素又取决于所部署的微电网的地理位置以及微电网运行所在地的网络风险状况。因此,在这项工作中,我们试图捕捉各种因素的多维相互作用,以量化微电网在这些不同方面的弹性能力。因此,本文提出了一个定制的站点特定的量化的弹性强度的个人微电网的能力,以吸收,恢复,并适应不断变化的情况下,维持临界负荷时,发生低概率高影响的事件-被称为上下文感知的弹性度量。我们还提出了一个案例研究,以说明我们的综合分析方法的关键要素。

英文摘要:

Microgrids present an effective solution for the coordinated deployment of various distributed energy resources and furthermore provide myriad additional benefits such as resilience, decreased carbon footprint, and reliability to energy consumers and the energy system as a whole. Boosting the resilience of distribution systems is another major benefit of microgrids. This is because they can also serve as a backup power source when the utility grid operations are interrupted due to either high-probability low-impact events like a component failure or low-probability high-impact events - be it a natural disaster or a planned cyberattack. However, the degree to which any particular system can defend, adapt, and restore normal operation depends on various factors including the type and severity of events to which a microgrid is subjected. These factors, in turn, are dependent on the geographical location of the deployed microgrid as well as the cyber risk profile of the site where the microgrid is operating. Therefore, in this work, we attempt to capture this multi-dimensional interplay of various factors in quantifying the ability of the microgrid to be resilient in these varying aspects. This paper, thus, proposes a customized site-specific quantification of the resilience strength for the individual microgrid capability to absorb, restore, and adapt to the changing circumstances for sustaining the critical load when a low-probability high-impact event occurs - termed as - context-aware resilience metric. We also present a case study to illustrate the key elements of our integrated analytical approach.
