本文阐明失负荷期望（LOLE）仅在受限条件下可作为频率指标，且与频率与持续时间（F&D）方法的标准频率指标有根本差异，避免误用。
AI 中文摘要
失负荷期望（LOLE）最初计算为预期失负荷天数，也被用作频率指标。本文表明，LOLE确实可以作为频率指标计算，但仅在受限条件下成立，并且它与频率与持续时间（F&D）方法中采用的标准频率指标存在根本差异。对这些条件缺乏理解可能导致错误的应用和解释。
英文摘要
Loss of Load Expectation (LOLE), originally calculated as the expected number of days of load loss, has also been used as a frequency metric. This paper shows that LOLE can indeed be calculated as a frequency metric, but only with restricted conditions, and that it differs fundamentally from the standard frequency metric employed in the frequency and duration (F&D) approach. A lack of understanding of these conditions can lead to incorrect applications and interpretations.
