Identification of coherent generators using fuzzy c-means clustering algorithm and construction of dynamic equivalent of power system

الملخص EN

This paper presents a new simple method to identify the coherent groups of generators based on two different techniques; the first one is based on six proposed coherency criterions introduced by using time response of the linearized power system model; the second one is based on the application of fuzzy c-means clustering algorithm (FCM).

A new technique of constructing the dynamic equivalent of power system is also presented in this work.

The results obtained by the first technique are compared to those obtained by FCM technique.

The proposed method is applied on 14-Bus IEEE power system.

The obtained results proved that the proposed method is highly effective in determining the coherent groups of generators and in constructing the dynamic equivalent of power system with high accuracy.
