Abstract :
We describe weaknesses in using deterministic methods for performing security assessment for bulk transmission systems. We also present motivation for using probabilistic risk and provide fundamental relations for making the associated calculations. The benefits and applications of using a risk index for security assessment are discussed, and an illustration is provided for line overload security assessment in the operational context
