Abstract
This paper concerns compute and exploiting the sensitivity of the loading margin to voltage collapse with respect to various parameters. The main idea of this paper is that after the loading margin has been computed for nominal parameters, the effect on the loading margin of altering the parameters can be predicted by Taylor series estimates. Loading margin is a fundamental measure of proximity to voltage collapse. Linear and quadratic estimates to the variation of the loading margin with respect to any system parameter or control are derived. The accuracy of the estimates over a useful range and the ease of obtaining the linear estimate suggest that this method will be of practical value in avoiding voltage collapse.Downloads
