N2 - This paper presents a novel algorithm for developing dynamic equivalents of large-scale power systems. Generators are identified to the coherent groups according to the relation factors, which represent the relative coupling degree between the generators. While the groups are identified, participation numbers - which are the measure of the relative participation of the generators in the group - are obtained. All generators and controllers in the group are weighted by participation numbers and aggregated to construct a dynamic equivalent. The proposed algorithm is applied to a 272-machine Korea Electric Power Corporation's system. The results indicate the accuracy and usefulness of the algorithm.
