[en] The PSA approach for transmission grid security presented in this paper is one of the security analysis methods for specific purposes; it is a probabilistic approach to assessing the risk of a system breakdown after grid faults, and observing system dynamics, too. Based on systematic and analytical modelling of post-fault events rather than on random sampling, the PSA approach can reveal the vulnerable parts of the system. The main objective is to increase the understanding of the system and reveal those components, where the improvements most effectively support the security after grid faults. The method uses event and fault tree analysis in combination with the dynamic stability analysis of the grid. (Authors)
