Güç sistemlerinde FACTS cihazları ve dağıtık üretim kaynakları kullanılarak gerilim kararlılığının ve yükleme kapasitesinin iyileştirilmesi

Öz

Gerilim kararlılığı, güç sistemlerinde incelenmesi gereken önemli bir konudur. Sürekli artan elektrik enerjisi talebi, artan talebi karşılamak için yeni elektrik üretim santrallerinin kurulumu ve güç sistem arızaları gerilim kararlılığını olumsuz yönde etkilemektedir. Günümüzde gerilim kararlılığını iyileştirmek için güç sistemlerinde Esnek Alternatif Akım İletim Sistemleri (FACTS cihazları) kullanılmakta olup, ayrıca enerji talebini karşılamak ve gerilim kararlılığını iyileştirmek için güç sistemlerine Dağıtık Üretim Kaynakları (DGs) entegre edilmektedir. Bu çalışmada, IEEE 30 baralı güç sistemi ile Kuzeybatı Anadolu (KBA) güç sistemi, gerilim kararlılığı bakımından temel (nominal), aşırı yüklenme ve hat kopması durumlarında incelenmiştir. İncelenen güç sistemlerine FACTS cihazlarından Statik Var Kompanzatör (SVC) ve Tristör Kontrollü Seri Kapasitör (TCSC), DGs’lerden ise Yakıt Hücresi (YH), Güneş Enerji Santrali (GES) ve Rüzgâr Enerji Santrali (RES) ayrı ayrı ve birlikte bağlanmıştır. Güç sistemlerinin bara gerilim değerlerinde ve yüklenme parametresinde meydana gelen değişimler analiz edilmiştir.

Improvement of voltage stability and loading capacity using FACTS devices and distributed generation resources in power systems

Öz

Voltage stability is an important issue to be studied in power systems. The ever-increasing demand of electrical energy, new power generation plant installations to meet the increasing demand to meet the increasing demand, and failures in the power system adversely affect the voltage stability. Today, Flexible Alternating Current Transmission Systems (FACTS devices) are used in power systems to improve voltage stability, and Distributed Generation sources (DGs) are integrated into power systems to meet energy demand and improve voltage stability. In this study, the IEEE 30 bus power system and the North-west Anatolia (KBA) power system are investigated in base (nominal), overload, and line outage cases regarding voltage stability. Static Var Compensator (SVC) and Thyristor Controlled Series Capacitor (TCSC) from FACTS devices, Fuel Cell (YH), Solar Power Plant (GES), and Wind Power Plant (RES) from DGs are connected separately and together in the power systems. Changes in bus voltage values and loading parameters of power systems are analyzed.
