Abstract
This work presents an assessment of the wind potential and a design methodology for a 10 MW wind farm in the Arzew industrial region, located in northwest Algeria, to improve the quality of service of the electricity grid and increase Algeria's participation in the use of renewable energy. The hourly wind data of 10 years (2005-2015) that correspond to the wind potential of the site were analyzed, such as: dominant wind directions, probability distribution, Weibull parameters, mean wind speed and power potential. The site has a mean annual wind speed of 4.46 m/s at 10m height, and enough space to locate the wind turbines. A comparative study was carried out between four wind turbine technologies to improve the site's efficiency and select the appropriate technology: PowerWind 56/ 900 kW, Nordex N50/800 kW, Vestas V50/850 kW, NEG-Micon 44/750 kW. The estimate of the energy produced using WAsP software and the choice of the optimal architectural configuration for wind turbines installation was confirmed. A techno-economic and environmental study was carried out by HOMER software, to choose the model that produces the maximum annual net energy with a competitive cost in the global wind energy market, $ 0.068/kWh, and that provides clean energy with a reduced emission of polluting gases. Finally, this work provides a good indicator for the construction of a wind farm in Arzew.
Highlights
The increase in electricity consumption in recent years due to the development of industrial and domestic receivers is causing an accelerated increase in pollution (Ozturk & Acaravci, 2010) (Halicioglu, 2009) (Ang, 2007)
WAsP (“Wind Energy Industry-Standard Software WAsP”.2017) software was used during this study to simulate the site parameters, with a database of wind parameters collected over a 10-year period by the metrology station in the Arzew region
A comparative study of several parameters such as annual energy production, losses by wake effect, mean annual wind speed and power density was conducted to optimize the overall efficiency of the wind farm, as shown in Tables 3 and 4
Summary
The increase in electricity consumption in recent years due to the development of industrial and domestic receivers is causing an accelerated increase in pollution (Ozturk & Acaravci, 2010) (Halicioglu, 2009) (Ang, 2007). The satisfactory solution for both sides of this equation (consumption and pollution) lies in the development of renewable energies (Edinger & Kaul, 2000) (Zhang, 2007) (Reiche & Bechberger, 2004) (Georgopoulou et al, 1998). The exploitation of these clean energies depends on the characteristics of the site's deposit. The difference in absorbed solar radiation causes temperature variations between regions, resulting in differences in air mass density and promoting air mass movement from one height to another.
