Abstract:

 Reactive power compensation investments are made for energy production, transmission and distribution systems. Currently, electricity distribution companies invest in reactors, capacitors and magnetically controlled reactors for reactive power compensation. With these investments, transmission companies receive reactive power support from existing production plants within the scope of ancillary services. Nowadays, with the increase in distributed generation facilities such as solar power plants SPPs and wind power plants WPP, the energy flow connected to the distribution grid has become bidirectional. In distributed generation facilities such as SPP and WPP, during hours when there is no production, the capacitive reactive originating from the conductors increases and the increase in production causes voltage rise in the region. In this study, the usability of SPPs for reactive power compensation was investigated in order to turn the disadvantages of distributed energy resources into advantages and to reduce compensation investment costs. For this purpose, necessary simulation studies were carried out to obtain reactive power support from a solar power plant connected to a transformer center in a electricity distribution region. Later, experimental studies were carried out by receiving reactive power support from the solar power plant in the region for seven hours. As a result, it has been emphasized that the reactive power support received from the solar power plant will reduce compensation investments.

 Enerji üretim, iletim ve dağıtım sistemlerinde reaktif güç kompanzasyonu için yatırım yapılmaktadır. Mevcutta elektrik dağıtım şirketleri reaktif güç kompanzasyonu için reaktör, kapasitör ve manyetik kontrollü reaktör yatrımı yapmaktadır. İletim şirketleri ise bu yatırımlara ek olarak mevcutta bulunann üretim santrallerinden yan hizmetler kapsamında reaktif güç desteği almaktadır. Günümüzde güneş enerji santrali GES, rüzgâr enerji santrali RES gibi dağıtık üretim tesislerinin artmasıyla birlikte dağıtım şebekesine bağlı enerji akışı çift yönlü hale gelmiştir. GES ve RES gibi dağıtık üretim tesislerinde üretim olmadığı saatlerde iletkenlerden kaynaklı kapasitif reaktifin artmasına ve üretimin artması ise bölgede gerilim yükselmesine neden olur. Bu çalışmada dağıtık enerji kaynaklarının dezavantajlarını avantaja çevirmek, kompanzasyon yatırım maliyetlerini azaltmak amacıyla GESlerin reaktif güç kompanzasyonu için kullanılabilirliği araştırılmıştır. Bunun için bir elektrik dağıtım bölgesinde bulunan bir trafo merkezine bağlı bir GESnden reaktif güç desteği alınması için gerekli simülasyon çalışmaları yapılmıştır. Daha sonra bölgedeki GESnden yedi saat boyunca reaktif güç desteği alınarak deneysel çalışmalar yapılmıştır. Sonuç olarak GESnden alınan reaktif güç desteği sayesinde kompanzasyon yatırımlarının azalacağı vurgulanmıştır.
