Abstract

The solar-hydroelectric (SHE) energy system is a renewable hybrid energy system consisting of solar and hydroelectric energy. An optimization algorithm has been designed to work out the installed power size of the SHE hybrid system, which is planned to be integrated into the existing hydroelectric power systems. This designed algorithm provides the optimum installed power with the benefit/cost approach. The value of the hydro cost and also the energy generation is taken from the actual values since it's an existing facility, and also the electricity production and price of the solar power are obtained from the algorithm that works iteratively. This study aims to indicate that more electricity will be produced by regulating water flows due to the reservoir of hydroelectric power plants. Hydro energy enables energy management to be administrated more effectively with the reservoir, which could be a natural enclosure, without using the other energy storage equipment/method. As a result of the study, it's been shown that with the regulation of the hydro facility flows with a reservoir, 180% more solar power capacity installation with 20.9 MW installed power and 12% more electricity production with 75.3 GWh electricity production is provided compared to the unregulated situation.

Hibrit Güneş-Hidroelektrik (GHE) Sistemine Rezervuar Etkisi

Abstract

Güneş-hidroelektrik (GHE) enerji sistemi, güneş ve hidroelektrik enerjisinden oluşan bir yenilenebilir hibrit enerji sistemidir. Mevcut hidroelektrik enerji sistemlerine entegre bir şekilde kurulması planlanan GHE hibrit sistem kurulu güç büyüklüğünün tespiti için bir optimizasyon algoritması tasarlanmıştır. Tasarlanan bu algoritma fayda/maliyet yaklaşımıyla optimum kurulu gücün elde edilmesini sağlamaktadır. Hidro enerji tesisinin maliyeti ve enerji üretimi mevcut bir tesis olduğundan gerçekleşen değerler üzerinden alınmış olup, güneş enerjisinin elektrik üretimi ve maliyeti ise döngüsel olarak çalışan algoritmadan elde edilmiştir. Bu çalışmanın amacı, hidroelektrik santrallerinin sahip olduğu rezervuar sayesinde su akımlarının düzenlenmesi ile daha fazla elektrik üretimi yapılabileceğini göstermektir. Hidro enerji başka bir enerji depolama ekipmanı/yöntemi kullanmadan doğal depolama alanı olan rezervuar ile enerji yönetiminin daha etkin bir şekilde yürütülmesine imkan sağlamaktadır. Yapılan çalışma sonucunda, rezervuarı olan hidro tesis akımlarının düzenlenmesi ile düzenlenmemiş duruma göre 20,9 MW kurulu güç ile %180 daha fazla güneş enerji kapasitesi kurulumuna ve 75.3 GWh elektrik üretimi ile de %12 daha fazla elektrik üretimine imkan sağlandığı gösterilmiştir.
