Abstract

This research at supplying electricity to Ziway lake islanders in Ethiopia, through studying the wind, pumped hydro-storage (PHS), and solar energy potentials. A wind mast is erected, and measurements at 10,50, and 70m heights are taken for a year long. The wind is of class-4 with wind speeds of 7m/s at 50m, and 7.87m/s. The energy density is 318.8 kWh/m2 (50m). GIS-based 3D digital elevation model (DEM) is used to investigate the PHS, with the lake as lower-reservoir and a dried-out crater pond of an extinct volcano as upper reservoir. The head is extracted using optical remote sensing technology, DEM(LiDAR) 12.5m. Constraints considered are topography, area, head, and slope. Twelve upper reservoirs are identified within head range of 50-250,50-200, and 50-100m. The results showed a PHS capacity of 5976 KWh at head of 60m can be developed. The solar energy potential is 6.1KWh/m2 /day. The finding proved the viability of electricity supply to the community.

可持续技术选择调查：风力、抽水蓄能和太阳能发电潜力，为埃塞俄比亚孤立的Ziway岛居民供电

这项研究旨在通过研究风能、抽水蓄能（PHS）和太阳能潜力，为埃塞俄比亚的Ziway湖岛民供电。架设了测风杆，并在10米、50米和70米的高度进行了为期一年的测量。风力等级为4级，50米处风速为7米/秒，7.87米/每秒。能量密度为318.8千瓦时/平方米（50米）。基于GIS的三维数字高程模型（DEM）用于研究PHS，以湖泊为下水库，以死火山干涸的火山口池塘为上水库。使用光学遥感技术提取水头，DEM（LiDAR）为12.5m。考虑的限制因素包括地形、面积、水头和坡度。在50-250、50-200和50-100m的水头范围内确定了12个上部储层。结果表明，在水头60米处可以开发5976千瓦时的PHS容量。太阳能潜力为6.1KWh/㎡/天。这一发现证明了向社区供电的可行性。

期刊介绍： With ICT pervading everyday objects and infrastructures, the ‘Future Internet’ is envisioned to undergo a radical transformation from how we know it today (a mere communication highway) into a vast hybrid network seamlessly integrating knowledge, people and machines into techno-social ecosystems whose behaviour transcends the boundaries of today’s engineering science. As the internet of things continues to grow, billions and trillions of data bytes need to be moved, stored and shared. The energy thus consumed and the climate impact of data centers are increasing dramatically, thereby becoming significant contributors to global warming and climate change. As reported recently, the combined electricity consumption of the world’s data centers has already exceeded that of some of the world''s top ten economies. In the ensuing process of integrating traditional and renewable energy, monitoring and managing various energy sources, and processing and transferring technological information through various channels, IT will undoubtedly play an ever-increasing and central role. Several technologies are currently racing to production to meet this challenge, from ‘smart dust’ to hybrid networks capable of controlling the emergence of dependable and reliable green and energy-efficient ecosystems – which we generically term the ‘energy web’ – calling for major paradigm shifts highly disruptive of the ways the energy sector functions today. The EAI Transactions on Energy Web are positioned at the forefront of these efforts and provide a forum for the most forward-looking, state-of-the-art research bringing together the cross section of IT and Energy communities. The journal will publish original works reporting on prominent advances that challenge traditional thinking.
