“…In a given site, to assess the feasibility of the wind farm, the cost of energy is the most important parameter to evaluate the economic viability. For evaluating wind energy cost, several methods have been discussed in [33]. However, the present value of costs (PVC) method is commonly used, and it is adopted in this study.…”

The use of small scaled horizontal and vertical axis wind turbines in urban installation is increasing over the world. However, in Djibouti, the latter is still in the development phase. The paper presents a techno-economical analysis and wind energy potential for the period of five years (2015-2019) in Nagad based on actual measured wind speed data collected every 10 min at 10 m height. The energy pattern factor method has been used to estimate the Weibull parameters. With this method, the mathematical complexity is reduced with a minimization of the error at any heights and locations when calculating the wind power density. At 50 m height, the shape parameter showed a small variation for different periods. The scale parameter values of 7.78 m/s and 4.8 m/s were obtained in the hot and cold seasons, respectively. The results showed that the Nagad site is suitable for wind power development. According to the economic viability, RX30, Vestas V20, Enercon, Nordex N27, and Vestas V44 wind turbines are recommended for the Nagad site due to their low energy price ranging from 0.05$/kWh to 0.31$/kWh. This is 2-6 times cheaper than the average local tariff of electricity in Djibouti.

“…Note that the construction of an economic model of wind turbines differs from one country to another and from one site to another. These include, among others, the work of Sukkiramathi and Seshaiah [58], Mostafaeipour et al [59], Touafio et al [60], Moria et al [61], and Kassem et al [62,63]. In addition, some authors have proposed modifications of the economic model using the PVC (present value cost) method and the CPU (cost production unitary or cost per unit) method (Said [64]).…”

This paper performs a technoeconomic analysis of the wind power potential and evaluates the cost of wind power generation in Evodoula, comparing two methods, the conventional method and the uncertainty method based on a comparative spatiotemporal approach using the geographic information system (GIS) software tool. This study is based on satellite wind data measured at 10 m above ground level (AGL) over a 40-year period (1980-2019), by the meteorological service NASA (National Aeronautics and Space Administration)/Goddard Space Flight Center (GSFC). The main objectives are to obtain an appropriate design for a proven optimal location and to assess the viability of wind power at Evodoula. For this type of study, there is little literature available. The optimization of an onshore wind farm and deployment in the wind energy development interest area (ZIDEE) is carried out to obtain a minimum and parsimonious discounted cost production unitary (CPU) of the electricity produced. The results showed that in Okok, a location with a large energy deficit, an onshore wind farm with an electricity generation capacity of 12.5 MW with 5 NORDEX N100-2.5MW wind turbines would have a total energy production (TEP) of about 64.0254825 TWh and a selling price of electricity that would be 0.0034 CAD$/kWh, which is very low compared to the utility price (about 98% cheaper). The total cost of the wind farm would be about $11 million, with a net present cost of about $218 million. The annual profit generated by the wind farm would be over $6 billion. The return on investment (ROI) of the project is estimated at 2880.882%. The constructed onshore wind farm would avoid CO2 emission at over 11 MtCO2,eq/year as the energy generated is from the atmosphere. The wind farm would realize an average annual cash flow estimated at nearly $30 million after 20 years of operation. These savings would allow the installation of CO2 capture systems in conventional power plants. In addition, the analysis of uncertainties and risks was identified and quantified to estimate the confidence levels of the project development results. The risks have been assessed, and we recommend that the total uncertainty of the project is around 15%. The energy values in P75 and P90 are 10.08% and 19.22%, respectively, lower than the energy value in P50 of 11.60 GWh/An. Finally, the main policy recommendations for an inclusive design process are highlighted. The contribution of this study is to assist policy makers in making appropriate decisions in the development and implementation of energy and environmental policy in Cameroon and in many continental areas.

Diseño mecánico de palas para un aerogenerador de 250w de potencia

Las zonas rurales tienen una deficiencia de suministro eléctrico importante, ya que las comunidades están alejadas de las redes de transmisión eléctrica, por lo que el desarrollo se delimita apresuradamente en estos lugares. En zonas de este tipo, donde se dispone del recurso renovable del viento, la implantación de máquinas eólicas o aerogeneradores puede representar una solución viable e inmediata al problema energético de necesidades eléctricas básicas. Los aerogeneradores están planificados para áreas con fuertes corrientes de viento para generar la energía, y los mismos presentan de manera más eficiente una solución viable e inmediata, especialmente para el problema energético de las necesidades eléctricas básicas. El diseño experimental propuesto se basó en la literatura existen sobre el diseño de palas para generadores eólicos tomando en cuenta las condiciones locales de áreas rurales de la República Dominicana que tengan las condiciones de viento mínima para que estas funcionen. Sin embargo, la indicación más significativa para seleccionar los materiales es la disponibilidad local. El diseño final presentado en las conclusiones es el resultado de una investigación teórica, una solución de ecuaciones matemáticas y un montaje experimental realizado en el Instituto Tecnológico de Santo Domingo, INTEC. Se espera que este trabajo sea un punto de partida para nuevas investigaciones relacionadas o mejoras al diseño actual en la República Dominicana.
