| Abstract | In this paper it will be studied the influence of the transient stability performance indices on a contingency screening and ranking algorithm. Due to the large number of contingencies scenarios and calculations required, it was applied a hybrid method to assess the system stability. The single dynamic security indices are obtained as a sub product of the hybrid method with a very reduce computing effort. The composed security indices are evaluated combining the single dynamic indices using weights. These indices are used to select, classify and rank the contingencies in accordance with the system security level. |
