Quick and effective multiple contingency screening algorithm based on long-tailed distribution

This study proposes a quick and effective algorithm for screening severe N - 2 contingency, thus avoiding exhausting analysis of all conceivable N - 2 contingencies. First, the index of overload contribution rate (OCR) is developed on the basis of distribution factor, which is discovered to be long-tailed distributed by statistics. Then, by fully exploiting the discovered feature, the so-called te...
