Proje Özeti

Bu proje çalışmasında, dinamik talep cevabı (DTC) kontrol çevrimi ve/veya elektrikli araç (EA) grupları içeren bir ve iki bölgeli yük frekans kontrol (YFK) sistemlerinin zaman gecikmesine bağlı kapsamlı bir kararlılık analizini sunulmaktadır. YFK sistemlerinde ölçüm birimleri ve haberleşme ağlarının yoğun kullanımından dolayı kaçınılmaz zaman gecikmeleri gözlenmektedir. Özellikle, sistemde yaşanan zaman gecikmeleri, sistemin dinamik performansını olumsuz etkileyerek kararlılık gecikme sınırının aşılması halinde sistemin kararsızlığına yol açabilmektedir. Dolayısıyla, elektrik güç sistemlerinin kararlılığı ve dinamik performansı üzerinde böylesi zaman gecikmelerinin etkisini incelemek önemlidir. Sistemin tolere edebileceği zaman gecikmesi üst sınırını hesaplamak için herhangi bir yaklaşıklık içermeyen iki analitik yöntem bu çalışmada önerilmiştir. Bu yöntemler frekans düzleminde tanımlanan Rekasius yerine koyma yöntemi ve üstel terimlerin yok edilmesi yöntemidir. Öncelikle, her iki yöntem kullanılarak EA toplayıcısı ve/veya DTC kontrol çevrimi içeren bir ve iki bölgeli YFK sistemlerinde oransal-integral (PI) denetleyici parametre değerlerinin tanımlanan bir seti için sistemin kararlılığını kaybetmeden tolere edebileceği kararlılık gecikmesi payları hesaplanmıştır. Daha sonra, herhangi bir zaman gecikme değeri için EA toplayıcısı ve/veya DTC kontrol çevrimi içeren bir ve iki bölgeli YFK sistemlerinin kararlılığını garantileyen tüm denetleyici kazanç değerlerini hesaplayan etkili bir grafiksel yöntem kullanılmıştır. Bu yaklaşım denetleyici parametre düzleminde kararlılık sınır eğrisini ve kararlılık bölgesini elde etmeye dayalıdır. Ancak, yenilenebilir enerji kaynaklarının güç dalgalanmaları, haberleşme zaman gecikmeleri ve sistem parametrelerindeki değişimlerden kaynaklanan belirsizlikten dolayı, EA toplayıcısı ve/veya DTC kontrol içeren YFK sistemlerinin tüm kararlı kılıcı denetleyici parametre değerleri istenilen dinamik performansı ve sistem kararlılığını garanti edemez. Gürbüz kararlılık problemini çözmek için, gürbüz PI denetleyici setini içeren gürbüz kararlılık bölgelerinin hesaplanması önemlidir. Parametrelerinin belirli bir aralıkta değiştiği YFK sistemlerinin gürbüz kararlılığını sağlamak için sadece dört polinom üzerine dayalı Kharitonov teoremi önerilmektedir. Son olarak, önerilen yöntemler kullanılarak elde edilen tüm teorik sonuçların doğruluğu benzetim çalışmaları ile gösterilmiştir.
