An integrated platform for power system security assessment implementing probabilistic and deterministic methodologies

Power system security assessment both for planning (off-line) studies and for operational (on-line) applications is performed by various analysis methods which highlight different phenomena (steady-state violations, angle stability, voltage stability, etc.) in order to retrieve an exhaustive vision of the problems. Besides traditional deterministic tools, recently proposed probabilistic tools may highlight new interesting security aspects by introducing the concepts of probability and quantifying the risk associated with the contingencies. This paper proposes the overall architecture of a security assessment platform which integrates both probabilistic and deterministic methodologies in a simple environment.
