Abstract
The main theme of this paper centers around the indent1f1cat1on of coherent groups in power systems for dynamic and transient stability studies. A proposed method which takes into account the effect of excitation systems is developed. The method has been tested through its application to a 31 bus system representing the unified power system of lower Egypt. The simulationresults showed the high capab1lity of the proposed method to identify the coherent groups in large scale power systems.

The need has been intensified for using dynamic equivalent modeling in power systems
Dynamic equivalent modeling using the coherency approach is based on the fact that groups of generators tend to oscillate t~gether for a particular disturbance
