Ekonomik güç dağıtımı, güç sistemlerinin planlanması ve işletimlerindeki en temel problemlerden biridir. Bu tür problemler sistem kısıtları altında toplam yakıt maliyetinin minimize edildikleri optimizasyon problemleridir. Bu çalışmada, generatörlerin artırma/azaltma sınırlarını dikkate alan yasak işletim bölgeli ekonomik güç dağıtımı problemi diferansiyel gelişim algoritması (DGA) ile çözülmüştür. Problemin çözümünde kullanılan iletim hatları ka yıpları B - kayıp matrisi ile hesaplanmıştır. DGA metodu literatürdeki 6 ve 15 generatörden oluşan iki farklı test sistemine uygulanmıştır. Elde edilen optimal çözüm değerleri, literatürde bulunan optimal sonuçlarla karşılaştırılmış ve sonuçlar tartışılmıştır.

The application of differential evolution algorithm for the economic power dispatch with prohibited operating zone

Öz

Economic power dispatch is one of the most leading problems in the power system planning and operation. This kind of problems in which total fuel cost is minimized under system limits. In this study, prohibited operating zone economic power dispatch proble m which considers ramp rate limit, has been solved by differential evolution algorithm (DGA). The transmission line losses used in the solution of the problem have been computed by B - loss matrix. DGA method has been applied to two different test systems in literature which consist of 6 and 15 generators. The attained optimum solution values have been compared with the optimum results in literature and have been discussed.
