这项工作探讨了美国最常见的中央发电厂类型所提供的可靠性权衡。从历史上看，电力行业对可靠性、弹性和脆弱性的差异以及这些指标如何根据电厂机组组成而变化缺乏共识。我们提出了不同的定义，这些指标和分析框架，以评估发电厂车队的可靠性。使用数据分析和文献综述，我们确定了15个可靠性属性，我们排名11个发电厂类型相对于天然气联合循环（NGCC）工厂。我们使用NGCC作为基准，因为它在许多地方都很常见，而且是相对较新的年份。该框架表明，每种类型的发电厂有独特的可靠性的优点和缺点。我们提供的例子，研究人员如何使用该框架来评估网格的可靠性定性在不同的情况下。我们发现，假设所有的属性，有助于电网的可靠性是同样重要的和添加剂，电网的可靠性是最好的支持时，发电厂的船队包括混合发电技术。然后，我们讨论了可能改变属性的优先级和关系的场景特征。我们还发现，如果目前的装机趋势继续有利于低碳和零碳发电厂，美国电网可能会受益于提高弹性和降低脆弱性，但代价是可靠性下降。最后，我们建议的方法，以适应框架和量化的属性之间的关系，在个别情况下。
This work explores the dependability tradeoffs provided by the most common types of central power plants in the United States. Historically, the electricity sector has lacked consensus on how reliability, resilience, and vulnerability differ and how those metrics change depending on the power plant fleet composition. We propose distinct definitions for these metrics and an analytical framework to evaluate power plant fleet dependability. Using data analysis and literature review, we identify fifteen dependability attributes across which we rank eleven power plant types relative to natural gas combined-cycle (NGCC) plants. We use NGCC as the benchmark because it is common to many locations and is of relatively recent vintage. The framework shows that each power plant type has unique dependability benefits and drawbacks. We provide examples of how researchers may use the framework to evaluate grid dependability qualitatively under different scenarios. We find that assuming all attributes that contribute to grid dependability are equally important and additive, electric grid dependability is best supported when power plant fleets include a mixture of power generation technologies. Then, we discuss scenario characteristics that could alter the prioritization and relationships of attributes. We also find that if current capacity installation trends continue to favor low- and zero-carbon power plants, US power grids may benefit from increased resilience and reduced vulnerability at the cost of decreased reliability. We conclude by recommending methods for adapting the framework and quantifying relationships between attributes in individual scenarios.
