Reduced order model for two areas to represent coherent groups in Power Electric Systems

The analysis of the frequency response of multi-area power systems is a complex and intensive task in the use of computational resources. This paper considers the implementation of a reduced model to represent coherent groups in a two area power system and the tuning of a synchronization coefficient, that represents the equivalent tie line. This work provides a basis for future analysis of more complex power systems, with three or more coherent areas.
