İyileştirilmiş su çevrim algoritmasıyla optimal yük akışı

Güç sistemlerinde üretim ve tüketim dengesinin sağlanabilmesi önemlidir. Optimum yük akışı (OYA) problemi generatörler, bara gerilimlerini, bara şönt reaktörlerini/kondansatörlerini kendi güvenli sınırlarında tutup, yakıt maliyeti ve aktif güç kayıplarını minimize etmeyi hedefler. Bu nedenle güç sistemlerinde OYA problemi etkili bir yöntemle çözülmelidir. Bu yayında, Su Çevrim Algoritması (SÇA) ve İyileştirilmiş Su Çevrim Algoritması (İSÇA) OYA problemine uygulanmıştır. Çalışmada, amaç fonksiyonu ile toplam yakıt maliyeti ve aktif güç kayıplarının minimizasyonu amaçlanmıştır. Yük akış problemi için önerilen optimizasyon algoritması IEEE 30 baralı test sistemine uygulanmıştır. İSÇA algoritması ile bulunan sayısal sonuçlar literatürde güncel olan diğer sezgisel algoritmalar ile karşılaştırarak, bu algoritmanın etkinliği, uygulanabilirliği ve esnekliği tartışılmıştır. Ayrıca bu algoritma 154 kV Güney Marmara iletim sisteminin bir kesitine uygulanmış ve iletim sistemine ait aktif güç kayıpları azaltılarak, uygun yük akış sağlanmıştır.
