The need for inexpensive and sustainable electricity has become an exciting adventure due to the recent rise in the local population and the number of visitors visiting the Banana Islands. Banana Islands is a grid-isolated environment with abundant renewable energy, establishing a hybrid renewable energy-based power system may be a viable solution to the high cost of diesel fuel. This paper describes a dual-flow optimization method for electrifying the Banana Islands, a remote island in Sierra Leone. The study weighs the pros and cons of maintaining the current diesel-based power setup versus introducing a hybrid renewable energy system that takes backup component analysis into account. Hybrid Optimization of Multiple Energy Resources (HOMER) software is used in the first optimization to optimally design the various system configurations based on techno-economic and environmental characteristics. A Multi-Attribute Decision-Making (MADM) Model that takes into account in the second optimization, the Combinative Distance-based Assessment System (CODAS) algorithm, and various methods of assigning weights to the attributes is used to rank the best configuration. The results show that the hybrid renewable energy system is a better option for electrifying the Banana Islands than the current stand-alone system. The Analytical Hierarchy Process (AHP) method of weight assignment was found to be superior to the Entropy method. Biogas generator-assisted hybrid configurations outperformed diesel generator-assisted hybrid configurations. With an optimum design of 101 kW PV, 1 wind turbine, 50 kW biogas, 86 batteries, and a 37.8 kW converter, the PV-wind-biogas-battery system is rated as the best configuration. It has a net present cost (NPC) of $487,247, a cost of energy (COE) of $0.211/kWh, and CO2 emission of 17.5 kg/year. Sensitivity analyses reveal that changes in the rate of inflation and the cost of storage have a significant effect on the overall cost of the configuration.

“…There have been many significant works done by researchers around the world on the Hybrid power system with renewable energy, which are either off-grid [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] or grid-connected [26][27][28][29][30][31][32][33]. In [7], Groppi et al focused on the hybrid storage (battery plus hydrogen) system while planning a smart energy system to ensure economic and environmental benefits.…”

Analysis of Techno-Economic-Environmental Suitability of an Isolated Microgrid System Located in a Remote Island of Bangladesh

Following a rise in population, load demand is increasing even in the remote areas and islands of Bangladesh. Being an island that is also far from the mainland of Bangladesh, St. Martin’s is in need of electricity. As it has ample renewable energy resources, a renewable energy-based microgrid system seems to be the ultimate solution, considering the ever-increasing price of diesel fuel. This study proposes a microgrid system and tests its technical and economic feasibility in that area. All possible configurations have been simulated to try and find the optimal system for the island, which would be eco-friendly and economical with and without considering renewable energy options. The existing power supply configuration has also been compared to the best system after analyzing and investigating all technical and economic feasibility. Sensitivity and risk analysis between different cases provide added value to this study. The results show that the current diesel-based system is not viable for the island’s people, but rather a heavy burden to them due to the high cost of per unit electricity and the net present cost. In contrast, a PV /Wind/Diesel/Battery hybrid microgrid appeared to be the most feasible system. The proposed system is found to be around 1.5 times and 28% inexpensive considering the net present cost and cost of energy, respectively, with a high (56%) share of renewable energy which reduces 23% carbon dioxide.

ÖzÇalışmamızda Konya ilindeki bir fabrikanın enerji ihtiyacını karşılamak için, şebekeye bağlı fotovoltaik (FV) güneş enerjisi sistemi, akü ve dizel jeneratörden oluşan hibrit bir sistem Çoklu Enerji Kaynakları İçin Hibrit Optimizasyonu (HOMER) yazılımı kullanılarak analiz edilmiş ve tasarlanmıştır. Analiz yapılırken, Konya'nın coğrafi pozisyonu, fabrikanın fiziksel ve ekonomik kısıtları gibi özellikler göz önünde bulundurulmuştur. Sistemin analiz ve tasarımı yapıldıktan sonra yıllar içerisinde gerçekleşmesi muhtemel FV panellerdeki verim düşümü, yükteki artış ve elektrik kesintileri gibi durumların sisteme olan etkisi incelenmiştir. Çalışmada değerlendirme kriterleri olarak net bugünkü maliyet (NBM) ve enerji maliyeti gibi parametreler göz önünde bulundurulmuştur. Simülasyon sonuçlarına göre fabrikanın günlük ortalama 1000 kWh olan elektrik ihtiyacının karşılanabilmesi için 3500 kW gücünde güneş paneli, 2400 kW gücünde dizel jeneratör, 55 kWh kapasiteye sahip batarya ve 2885 kW gücünde konvertör önerilmiştir. Bu sistemin NBM değeri 7.81 M$ olup yatırım maliyeti 1.94 M$ seviyesindedir. FV panellerde gerçekleşen %0.81'lik yıllık verim kaybı düşünüldüğü takdirde NBM %7.94, enerji maliyeti %11.16 oranında artmış ve sistemdeki yenilenebilir enerji kaynakları (YEK) oranı %5.74 oranında azalmıştır. Elektrik enerjisi talebinin artış oranı yıllık %2 olarak düşünüldüğü zaman NBM %42.13, enerji maliyeti %24.29 artmıştır. Sanayide gerçekleşen elektrik kesintilerinin değerlendirildiği durumda NBM %2.56, enerji maliyeti %2.87 oranında artmıştır. Sonuç olarak, önerilen hibrit enerji üretim sistemi ile fabrikanın elektrik ihtiyacı güvenilir şekilde sağlanabilmektedir.
