THE ANALYSIS OF IMPACTS OF A PV SYSTEM ON THE DISTRIBUTION SYSTEM RELIABILITY

Abstract

Today, in line with the increasing population and also with the increasing demanded energy, the tendency towards alternative energy sources has increased. As a result, the use of renewable energy sources (RES) is increasing day by day and especially the use of solar energy is becoming widespread. The use of solar energy has gained an important place in the current energy market because of its clean and economical feature. Malfunctions are one of the significant problems in solar power plants (SPP) as in every system. There is a distribution between the consumer demanding energy and the electricity transmission system. It is not desired to be affected of areas where the distribution network is located in case of any malfunction that may occur in these systems. For that purpose, the system must be reliable in order to ensure the continuity of the system. The ability that fulfilling the desired tasks during their operation is called reliability. The reliability analysis of a solar power plant (SPP) integrated into the distribution system has been made conducted for this purpose in this study. SPP has been designed with a simulation program to the place determined in Büyükçekmece which is the district of Istanbul. In this study, 3014 Canadian solar 320wp panels and ABB 5.k kW inverter have been used in a 5113m2 area. The energy analysis to be generated power in 365 days of a power plant is to produce 1000kwp power in total has been done in a simulation program. The daily load curve has been obtained by using monthly and hourly consumption information.

BİR GÜNEŞ ENERJİ SİSTEMİNİN DAĞITIM SİSTEMİ GÜVENİLİRLİĞİNE ETKİLERİNİN İNCELENMESİ

Abstract

Günümüzde artan nüfus doğrultusunda talep edilen enerjinin de artmasıyla, alternatif enerji kaynaklarına yönelim artmıştır. Bu nedenle yenilenebilir enerji kaynaklarının (YEK) kullanımı gün geçtikçe artmakta ve özellikle güneş enerjisinin kullanımı yaygınlaşmaktadır. Güneş enerjisinin kullanımı, temiz ve ekonomik olmasından dolayı mevcut enerji piyasasında önemli bir yer elde etme yolunda ilerlemektedir. Güç sistemleri yönetiminin öncelikli hedeflerinden bir kaliteli ve güvenilir enerjinin tüketiciye sağlanmasıdır. Her sistemde olduğu gibi GES’lerde de önemli sorunlardan biri arızalardır. Enerji talep eden tüketici ile elektrik iletim sistemi arasında dağıtım sistemi bulunmaktadır. Bu sistemlerde meydana gelebilecek herhangi bir arıza durumunda, arızadan sadece dağıtım şebekesinin bulunduğu bölge etkilenmesi istenmemektedir. Bu amaçla sistemin sürekliliği sağlanabilmesi için sistemin güvenilir olması gerekmektedir. Dağıtım sistemlerinin çalıştığı süre boyunca istenilen görevleri yerine getirebilmesine güvenilirlik denmektedir. Bu amaç doğrultusunda yapılan bu çalışmada, dağıtım sistemine entegre edilmiş bir güneş enerjisi santralinin (GES) güvenilirlik analizi yapılmıştır. İstanbul ili Büyükçekmece ilçesinde belirlenen yere bir benzetim programıyla GES tasarlanmıştır. Bu çalışmada 5113 m² alan içinde 3014 adet Canadian Solar 320 Wp panel, ABB 5.k kW invertör kullanılmıştır. Toplamda 1000 kWp güç üretecek santralin, bir benzetim programında 365 gün üreteceği enerjinin analizi yapılmıştır. Aylık ve saatlik tüketim bilgisi kullanılarak projenin günlük yük eğrisi elde edilmiştir.
