容量信用被广泛用于量化不同发电技术支持需求的能力。大多数实际的能力信贷计算是基于详细的风险建模，但也使用了各种简化方法。本文提出了一个重要的审查这些简化的方法，范围从年峰值计算和概率表示风，小装机容量推导出的封闭形式的表达式。主要的主题是，简化的方法必须保留手头的问题的关键特征，并且要感兴趣的简化方法必须要么带来实质性的计算优势，要么提供更多的洞察力，从更详细的风险计算。
Capacity credits are widely used to quantify the ability of different generating technologies to support demand. Most practical capacity credit calculations are based on detailed risk modelling, however a wide range of simplified approaches are also in use. This paper presents a critical review of these simplified approaches, ranging from annual peak calculations and probabilistic representations of wind, to closed-form expressions derived for small installed wind capacities. The principal themes are that simplified methods must retain the key features of the problem at hand, and that to be of interest simplified methods must either bring substantial computational advantages, or provide additional insight beyond that from a more detailed risk calculation.
