Abstract

Morocco has pursued an ambitious policy aimed at boosting renewable energies in the country. On this basis, we have examined the possibility of using wind turbines to generate electricity in Lamhiriz village in the south of Morocco, known for its strong winds. The wind speeds were statistically studied using the data recorded over one-year period collected from the mast which contains a set of measuring instruments at different altitudes. Based on several studies, we selected Weibull distribution to model the wind speeds, and we used the empirical method to estimate the scale and the shape parameters. Thereafter, a detailed analysis of seasonal and annual wind direction was presented. From the obtained results, the available energy density in this area is assessed by using WAsP software. Then, six commercial wind turbines of various sizes between 300 and 1300 kW were technically evaluated for electricity generation in Lamhiriz village by calculating their capacity factors and annual energy outputs. The results showed that the site under study is an adequate location for any of the adopted wind turbine models, where the annual energy output ranges from 1.44 to 6.75 GW h. Therefore, we can conclude that Lamhiriz have an attractive economical potential for developing large wind turbine farms.

摩洛哥Lamhiriz村的风数据分析和风能潜力评估

摘要

摩洛哥推行了一项雄心勃勃的政策，旨在促进该国的可再生能源。在此基础上，我们研究了在摩洛哥南部以强风闻名的Lamhiriz村庄中使用风力涡轮机发电的可能性。使用从桅杆收集的一年期间记录的数据对风速进行统计研究，该桅杆包含一组不同高度的测量仪器。基于多项研究，我们选择了Weibull分布来模拟风速，并使用经验方法来估计尺度和形状参数。此后，对季节和年度风向进行了详细分析。根据获得的结果，使用WAsP软件评估该区域中的可用能量密度。然后，通过计算Lamhiriz村的容量因子和年发电量，对六台大小在300至1300 kW之间的商用风力涡轮机的发电进行了技术评估。结果表明，所研究的站点对于任何采用的风力涡轮机模型都是适当的位置，其年能量输出范围为1.44至6.75 GW h。因此，我们可以得出结论，Lamhiriz具有发展大型风力涡轮机场的诱人的经济潜力。
