Bu çalışmada, kesir dereceli oransal - integral (FOPI) denetleyici içeren zaman gecikmeli bir bölgeli yük frekans kontrol (YFK) sisteminin kazanç ve faz payı (GPM) tabanlı kararlılık analizi gerçekleştirilmiştir. YFK sistemlerinin kontrolünde açık haberleşme ağlarının yoğun kullanımı sistemde zaman gecikmelerinin yaşanmasına neden olmaktadır. Meydana gelen zaman gecikmesi değerlerini hesaplamak için, istenilen GPM değerleri ve FOPI denetleyicinin farklı parametre değerlerinde karakteristik denklemin sanal eksen üzerindeki köklerini hesaplayan analitik bir yöntem önerilmiştir. Son olarak, Matlab/Simulink ortamında yapılan benzetim çalışmaları ve zaman gecikmeli sistemlerde köklerin konumu hakkında bilgi veren QPmR algoritması yardımıyla FOPI denetleyici içeren bir bölgeli YFK sistemi için elde edilen sonuçlar doğrulanmıştır.
