In this paper, the critical clearing time, t cc in power system transient stability analysis is modeled as a random variable due to the randomness nature of power system load. A linear approximation approach that mainly involves the sensitivity calculation of the derivative of t cc to system load is developed to obtain the probability density function (pdf)(More)
This paper presents a linear approximation method to determine the probability density function (PDF) of the critical clearing time (CCT) and probability of stability for a given disturbance in power system transient stability analysis. The CCT is the maximum time interval by which the fault must be cleared in order to preserve the system stability. The CCT(More)
