摘      要:A simple and efficient method for optimal selection of weights, along with higher order performance indices for voltage contingency selection, has been suggested in this ***. Some of the existing performance indices for voltage contingency selection has been critically reviewed. The proposed performance indices are able to eliminate misranking and masking effects. The post-outage quantities have been computed, using a new set of distribution factors, defned in terms of pre-outage real and reactive power flows in transmission lines/ outputs of generators. The proposed algorithm has been tested on IEEE 14-bus system and a practical 75-bus Indian system.
