Abstract

Güç sistemlerinin büyük boyutlara ulaşması ve uluslararası elektrik enerjisi ticaretinin artmasıyla birlikte, bölgeler arası elektrik enerjisi alışverişi de önem kazanmıştır. Duyarlılık faktörleri ile, farklı çalışma noktaları için tekrar bir güç akışı analizi yapmadan, iletim hatları ve diğer sistem elemanlarının parametreleri hakkında geniş bilgi edinilebilir. Bu durumda, iletim hattı kapasiteleri ve üretim gruplarının sınır değerleri hesaba katılarak bölgeler arası maksimum elektrik enerjisi alışverişinin sağlanması bir optimizasyon problemi olarak ele alınabilir. Bu çalışmada, güç iletim dağılım faktörü ve farklı optimizasyon yöntemleri kullanılarak, dört bölge, onbir bara ve onsekiz iletim hattndan oluşan güç sisteminde, üretim değerleri optimize edilerek, bölgeler arası elektrik enerjisi alışverişi maksimize edilmiştir.

ABSTRACT

Since size of the power systems and  demand for electric energy trading increases,  inter area transfer  capability becomes an important issue. By using sensitiviy factors, large amount of information about different operating points of power systems, can be obtained without power flow analysis.Providing maximum power transfer between areas  of power systems while considering capacities of transmission lines and generation limits, can be thought as an optimization problem. In this study,  power transfer distribution factor (PTDF) and different optimization methods are used to optimize generation  values for providing maximum power transfer between areas of power system consists of four areas, elevenbusses and eighteen transmission lines.
