Abstract：
As the population of Somaliland continues to grow rapidly, the demand for electricity is anticipated to rise exponentially over the next few decades. The provision of reliable and cost-effective electricity service is at the core of the economic and social development of Somaliland. Wind energy might offer a sustainable solution to the exceptionally high electricity prices. In this study, a techno-economic assessment of the wind energy potential in some parts of the western region of Somaliland is performed. Measured data of wind speed and wind direction for three sites around the capital city of Hargeisa are utilized to characterize the resource using Weibull distribution functions. Technical and economic performances of several commercial wind turbines are examined. Out of the three sites, Xumba Weyne stands out as the most favorable site for wind energy harnessing with average annual power and energy densities at 80 m hub height of 317 kW/m2 and 2782 kWh/m2, respectively. Wind turbines installed in Xumba Weyne yielded the lowest levelized cost of electricity (LCOE) of not more than 0.07 $/kWh, shortest payback times (i.e., less than 7.2 years) with minimum return on investment (ROI) of approximately 150%.
摘要：
随着索马里兰人口继续快速增长，预计未来几十年电力需求将呈指数级增长。提供可靠和具有成本效益的电力服务是索马里兰经济和社会发展的核心。风能可能为异常高的电价提供可持续的解决方案。在这项研究中,对索马里兰西部地区某些地区的风能潜力进行了技术经济评估。使用Weibull分布函数，利用首都哈尔格萨附近三个地点的风速和风向测量数据来表征资源。研究了几种商用风力涡轮机的技术和经济性能。在这三个网站中，XumbaWeyne是风能利用的最有利地点，其80m轮毂高度的年平均功率和能量密度分别为317kW/m2和2782kWh/m2。安装在XumbaWeyne的风力涡轮机产生的最低电力成本（LCOE）不超过0.07$/kWh，最短的投资回收期(即，少于7.2年)，最低投资回报率(ROI)约为150%。
