Abstract
The estimation of the accuracy of reduced order models or dynamic equivalents, for use in transient stability studies is investigated. Balanced realization theory is combined with modal coherency analysis to provide accurate estimates for dynamic equivalents based on coherency aggregation techniques. Test results for 23 and 86 generator systems are provided.Keywords
