Abstract :
Margin sensitivity is useful in determining the effectiveness of different parameters for the purpose of enhancing system loading margin. The paper shows that determining margin sensitivity is equivalent to a predictor stage of a continuation technique similar to CPF and that for cases in which sensitivity is not adequately accurate adding a few corrector steps would leads to better results. The paper also shows how two parameter continuation technique can be adapted to assess the effect of different controls on loading margin.
