Abstract	This paper presents a new approach for contingency selection in power system cyclic security analysis. A fast selection algorithm based on information available in the contingency analysis results from previous cycles and on the local network solution concept applied to two levels of contingency selection is developed. In order to reduce both the number of calculations required for security analysis and the time spent for Jacobian refactorization, a fast pre-screening process without load flow solution is designed initially. The PRESAF module (PRE-Selection Assistee par Filtre) proposed in this phase allows large sets of candidate contingencies to be processed very quickly. Then, a fast screening phase with the SAF module (Selection Assistee par Filtre) processes a small list of selected potentially severe contingencies. Tests on a 206 bus-299 branch 400 kV French model show that the proposed approach is fast and reliable for power system cyclic security analysis.
