Bu çalışmada, dinamik talep cevabı (DTC) ve haberleşme zaman gecikmesi içeren iki bölgeli yük frekans kontrol (YFK-DTC) sisteminin kararlılık sınır eğrisi yöntemi kullanılarak denetleyici parametre düzleminde kararlılık bölgeleri hesaplanmıştır. DTC kontrol, kontrol edilebilir yük gruplarını frekans kontrol servisine dahil ederek, üretim ve puant yük talebi arasında dengenin daha kısa sürede sağlanması ve yenilenebilir enerji kaynaklarında güç dengesizlikleri problemlerine karşı önemli bir çözüm sunmaktadır. DTC kontrol mekanizmasının yük frekans kontrol sistemlerinde kullanımı, sistemin güvenliği ve güvenilirliğini sağlamasına rağmen, haberleşme ağlarından kaynaklanan zaman gecikmeleri, denetleyici performansını ve sistemin kararlılığını olumsuz etkileyebilmektedir. Dolayısıyla, bu çalışma zaman gecikmesi içeren iki bölgeli YFK-DTC sisteminin kararlılığını garanti edecek tüm oransal-integral (PI) denetleyici kazanç değerlerini elde etmektedir. Bu amaçla, zaman gecikmeli YFK-DTC sisteminin denetleyici parametre düzleminde kararlılık bölgelerini oluşturan kompleks kök sınır (Complex Root Boundary, CRB) eğrisini ve reel kök sınır (Real Root Boundary, RRB) eğrisini bulmak için kararlılık sınır eğrsi yöntemi kullanılmıştır. Elde edilen teorik sonuçların doğruluğu, quasi-polynomial mapping root (QPmR) algoritması ve zaman düzleminde yapılan benzetim çalışmaları ile gösterilmiştir. Sonuçlar, DTC kontrol çevriminin katkısı ile zaman gecikmeli YFK sisteminin kararlılık bölgelerinin ve kararlılık payının arttığını göstermektedir.
