Bu çalışmada, dağıtık üretim (DÜ) sistemlerinin optimum şebeke entegrasyonu probleminin çözümü için zıtlık tabanlı parçacık sürü optimizasyonu (OBPSO) kullanımı önerilmektedir. Önerilen OBPSO yöntemi, DÜ’nün optimum yer ve büyüklük değerlerini bulurken çok amaçlı optimizasyon yaklaşımı kullanmaktadır. Ayrıca yük değişimlerine karşı duyarlılık analizi yöntemi ortaya konmuş ve yeni bir amaç fonksiyonu olarak da kullanılmıştır. Amaç fonksiyonları, aktif güç kaybı, gerilim değişimi ve duyarlılık analizi minimizasyonundan oluşmaktadır. DÜ kaynağı olarak fotovoltaik tabanlı güneş enerji sistemleri (DGES) esas alınmıştır. Birim güç faktörü ile işletilen 3 adet DGES eklendiği durumlar değerlendirilmiş ve amaç fonksiyonlarının değişimleri analiz edilmiştir. Önerilen metodun etkinliği standart test sistemlerinden IEEE 33 baralı dağıtım sistemi kullanılarak araştırılmıştır. Yük akışı analizi içi MATPOWER paket programı kullanılmıştır. Elde edilen sonuçlar literatürde bulunan diğer çalışmalarla karşılaştırılmıştır. Neticede, OBPSO yönteminin iyi sonuç verdiği ve karşılaştırılan diğer optimizasyon tekniklerine karşı üstünlükleri olduğu gözlenmiştir. Ayrıca, DGES’nin optimum değerler dikkate alınarak yapılan entegrasyonlarda amaç fonksiyonlarında belirgin iyileşmeye sağladığı gözlenmiştir.

Determining the Optimum Size and Siting of Distributed Solar Energy Systems Using OBPSO

Öz

In this study, OBPSO is proposed to solve optimal grid integration of distributed generation (DG) systems. While the proposed OBPSO method finds the optimum location and size values of DG, three different singular objective functions are considered. Additionally vulnerability analysis method to load changes is proposed and used as a new objective function. Objective functions consist of active power loss, voltage variation and vulnerability analysis minimization. Photovoltaic solar energy systems (DPVG) are considered as a source of DG. The cases where 3 DGES are added with the unit power factor are considered and the changes of the objective functions are evaluated. The efficiency of the proposed method is achieved by using IEEE 33 bus distribution system, which is one of the standard test systems. MATPOWER package program is used for load flow analysis. Then, the effectiveness of the proposed method is compared with other studies in the literature. The results obtained showed that OBPSO is effective and give better results against other optimization techniques compared in the study. It has been observed that DGES systems provide significant improvement in the purpose functions in the integrations made by considering the optimum values.
