In this study, optimal power management strategy to make optimal operation of the alternative sources has been considered to meet the load demand of heating, ventilations and air conditioning (HVAC) units for public institutions, hospitals, schools, etc. A hybrid power system consisting of wind türbine (WT), photovoltaics (PV) and battery has been proposed. The system is modelled to be used in an optimal demand response application. Moreover, the grid has been added to the hybrid power system due to the intermittent generation characteristics of alternative power sources. The objectives defined by the optimization problem are the operation of the alternative power sources at maximum rate and primarily meeting the HVAC load demand by the relevant sources. The resulting mixed-integer linear programming model is tested in GAMS v.24.1.3 platform using the solver CPLEX v.12.

HİBRİT GÜÇ SİSTEMİ İLE İKLİMLENDİRME YÜKLERİNİN OPTİMAL İŞLETİM MODELİ VE HASTANE İKLİMLENDİRME YÜKLERİ İÇİN TALEP CEVABI UYGULAMASI

Öz

Bu çalışmada, kamu kuruluşları, hastane, okul vb. gibi kurumların iklimlendirme cihazlarının yük talebinin karşılanmasında alternatif enerji kaynaklarından optimal olarak yararlanma stratejisi ele alınmıştır. İklimlendirme yüklerinin karşılanmasında rüzgar türbini (RT), güneş pili (GP) ve batarya (Bat) ile teşkil edilen hibrit güç sistemi önerilmiştir. Hibrit güç sistemi optimal talep cevabı uygulamasında kullanılmasına imkan verecek şekilde modellenmiştir. Ayrıca, hibrit kaynakların kesintili üretim karakteristikleri gereği hibrit güç sistemine şebeke gücü de ilave edilmiştir. Optimizasyon probleminde alternatif enerji kaynaklarının maksimum kapasitede kullanımı ve ilgili kaynakların öncelikli olarak iklimlendirme yüklerinin talebine cevap verecek şekilde kullanımı amaç olarak belirlenmiştir. Elde edilen karışık tamsayı lineer programlama modeli GAMS v.24.1.3 ortamında CPLEX v.12 çözücüsü ile test edilmiştir. Kış ve yaz koşulları dikkate alınarak optimal işletim modelinin benzetim çalışmaları yapılmıştır ve ilgili sonuçlar sunulmuştur.
