“…In order to obtain more realistic picture of the true wind energy potential, and also to stimulate broader support for the development and use of the RES in the Republic of donia, further research and measurements on determined locations are required [11]. Thorough financial analysis is also required in order to estimate profitability of such locations in terms of wind power utilization [12]. Preliminary Atlas of winds determined that the best wind resources in Macedonia are on the mountain tops, whereas on the plains and in the valleys, wind has lower average velocity.…”

Wind energy as a renewable energy source with the highest growth rate in the last two decades, is considered as a very important source of electricity for the future. The forecasts for development of wind energy are highly optimistic and state that this type of energy will be really important in the future. Following recent data and analysis from certain studies, the share of wind energy in the global world electricity generation in 2020 is estimated to reach 12%. In the same context, and in order to reduce high dependence on fossil fuels, Macedonian government took some steps to introduce and enforce utilization of renewable energy sources. First wind park with capacity of 36.8 MW, installed and operated by the state-owned electricity producing company (JSC Macedonian Power Plants-ELEM), started with operation in April 2014, on a location near Bogdanci. The techno-economic analysis regarding its performance in terms of investment costs, operation and maintenance costs, electricity production and return on investment period, considering valid feed-in tariffs for wind energy production in the country is also presented in the article.

“…Important research was done on atmospheric turbulence [9] and the methods of measuring wind potentials in the complex mountainous terrains of Serbia [10]. There are some papers considering the wind influence on other renewable energy sources [11], energy storage [12,13] and advanced simulation models [14,15].…”

Wind power assessment in complex terrain is a very demanding task. Modeling wind conditions with standard linear models does not sufficiently reproduce wind conditions in complex terrain, especially on leeward sides of terrain slopes, primarily due to the vorticity. A more complex nolinear model, based on Reynolds averaged Navier-Stokes equations have been used. Turbulence was modeled by modified two-equations k- model for neutral atmospheric boundary layer conditios, written in general curvelinear nonorthogonal coordinate system. The full set of mass and momentum conservation equations as well as turbulence model equations are numerically solved, knowing as computational fluid dynamics (CFD) technique. A comparison of the application of linear model and nonlinear model is presented. Considerable discrepancies of estimated wind speed have been obtained using linear and nonlinear models. Statistics of annual electricity production vary up to 30% of the model site. Even anemometer measurements directly at a wind turbine's site do not necessarily deliver the results needed for prediction calculations, as extrapolations of wind speed to hub height is tricky. The results of the simulation are compared by means of the turbine type, quality and quantity of the wind data and load factor. Finally, the comparison to the results with the measured data at 10, 30 and 50m.
