The Use of Probabilistic Approach in Power System Security Analyses

Abstract

The article describes the possibilities and methods of using the probabilistic approach in the field of power system security analyses. The calculations in contingency states were carried out assuming determined outages and probability outages. In the probabilistic approach, individual outages are treated according to the frequency of their occurrence, and not as certain events. Outages with very low probability are ignored, which affects the direction of long-term investments.
