摘要：

This letter proposes a method to model the power converter availability for power system adequacy assessment. The proposed method considers wear-out as well as chance failures and calculates an equivalent failure rate accordingly. In this regard, it is shown that neglecting the wear-out failures and the dynamic behavior of adequacy indices can lead to considerable errors. Moreover, the performance of the proposed availability modeling method is compared to that of the existing solutions through calculating the Expected Energy Not Supplied (EENS) in a case study. The comparison confirms the superior performance of the proposed method in terms of high accuracy and low computational burden.
