Özet

Reaktif güç, güvenlik ağızlarının ve ekonomik yüzlerin güç şebekelerinin çalışması için kritik öneme sahiptir. Reaktif

gücün mantıksız dağılımı, güç şebekelerinin güç kalitesini ciddi şekilde etkiler ve iletim kaybını arttırır. Halihazırda,

reel güç kaybını en aza indirgemenin en ekonomik ve pratik yaklaşımı, reaktif güç dağıtım yöntemi kullanılarak

kalmaktadır.

Reaktif güç dağıtımı problemi doğrusal değildir ve eşitlik kısıtlamaları ve eşitsizlik kısıtlamaları vardır. Bu tezde,

reaktif güç dağıtımı problemini çözmek için PSO algoritması ve MATPOWER 5.1 uygulanmıştır. PSO mükemmel

arama yeteneği ile donatılmış küresel bir optimizasyon tekniğidir. PSO’nun en büyük avantajı, PSO’nun verimliliğinin

nesnel işlevin karmaşıklığına daha az duyarlı olmasıdır. MATPOWER 5.1, güç akışı problemlerini çözmeye odaklanan

açık kaynak MATLAB kodudur. MATPOWER’ın faydası, kodunun kolayca kullanılması ve değiştirilebilmesidir.

Abstract

Power Networks have two major aspects one is the Safety of the network and the other is its economic, reactive

power is the very important element to serve these two aspects. To avoid unwanted power quality and high

transmission loss we should locate reactive power in reasonable way in power network. Currently, in order to

keep the network voltage in acceptable range and the real power loss as minimum we use dispatch of reactive

power in traditional way.

Since the reactive power has inequality constrains and quality constrains, so we can consider it as a nonlinear

problem. In my thesis, I will use MATPOWER 5.1 toolbox, PSO algorithm and matlab program and applied it to

find the optimum reactive power dispatch allocation. The algorithm PSO is a comprehensive optimization algorithm

that is equipped with the best searching ability. Advantage (major ones) of the PSO is that when the function

of the object is more complex the efficiency of PSO does not effect. Because MATLAB toolbox is a global program

and our work focus on power flow so we will use MATPOWER 5.1 as open source to solve the problem. Since

MATPOWER Toolbox is a power source so when any one use it, it will help him and the code will be very easy. Also

we will use OpenDSS program via MATLAB COM to see PV effect.

Then we will discuss the effect of PV residential penetration via MATLAB simulation using 24 house examples with

PV and without PV penetrations.

Our goal is to minimize power loss in transmission lines and to allocate the reactive power in optimal placement.

IEEE 24 bus system is used to calculate the performance.
