Genetik algoritma kullanılarak güç sistemlerinde optimal çalışma şartlarının belirlenmesi

Bu çalışmada optimizasyon yöntemlerinden biri olan Genetik Algoritma (GA) ile elektrik güç sistemlerinde optimum çalışma koşulları belirlenmiştir. Çalışmanın ana hedefi iletim hatlarında meydana gelen aktif güç kayıplarının minimum olmasını sağlayacak yük baralarının gerilim genlik değerlerinin belirlenmesidir. Örnek olarak 5 baralı bir sistem ele alınmış ve bu sistem üzerinde hem GA hem de Newton-Raphson (NR) güç akışı yöntemi kullanılarak yük baralarının çalışma gerilim değerleri belirlenmiştir. Bu değerler kullanılarak Statik VAR Kompanzatör (SVC) ile reaktif güç kompanzasyonu yapılmıştır. Elde edilen sonuçlar, GA ile çalışma koşullarının belirlenmesi durumunda aktif güç kayıpları minimize edileceğinden ciddi oranda ekonomik kazanç ve enerji tasarrufu sağlanacağını ortaya koymaktadır.

Determination of the conditions of optimal operation in power systems using genetic algorithm

In this study, optimum operating conditions in electric power systems are determined by using Genetic Algorithm (GA), which is one of the optimization methods. Main objective of the work is determination of the voltage amplitude values of the load buses that ensure active power losses in transmission line will be minimum. A five-buses system is considered as an example and the operating voltage values of the load buses are calculated for this system using both GA and Newton-Raphson (NR) power flow method. Using these values, Static VAR Compensation (SVC) and reactive power compensation are implemented. Results show that it will be economically and energy-providently if the operating conditions are determined using GA, since the active power loss is minimized.
