Probabilistic reliability calculation of transmission networks

This paper describes the application of a probabilistic reliability calculation method to a countrywide transmission network in an actual case study. The calculation method and certain general aspects of reliability analyses in the transmission level are presented at first. The case study is introduced, and special considerations on defining suitable parameters for the Markov-based calculation algorithm are discussed. The main results of the reliability analysis are summarized, and an updated scenario of the system verifies selected improvements derived from these results.
