Comparison of roughness index for Kitka and Koznica wind farms

Abstract

<span lang="EN-US">Kosovo has limited renewable energy resources and its power generation sector is based on fossil fuels. Such a situation emphasizes the importance of active research and efficient use of renewable energy potential. According to the analysis of meteorological data for Kosovo, it can be concluded that among the most attractive potential wind power sites are the locations known as Kitka (42° 29' 41" N and 21° 36' 45" E) and Koznica (42° 39′ 32″ N, 21° 22′30″E). The two terrains in which the analysis was carried out are mountain areas, with altitudes of 1142 m (Kitka) and 1230 m (Koznica). the same measuring height, about 84 m above the ground, is obtained for these average wind speeds: Kitka 6,667 m/s and Koznica 6,16 m/s. Since the difference in wind speed is quite large versus a difference in altitude that is not being very large, analyses are made regarding the terrain characteristics including the terrain relief features. In this paper it will be studied how much the roughness of the terrain influences the output energy. Also, that the assumption to be taken the same as to how much they will affect the annual energy produced.</span>

Role of wind energy in sustainable development in coal-based systems: Case of Kosovo

“…All possible wind farms are located in mountainous terrain [22]. For the studies conducted in Kitka, Koznica, Bajgora and Zatriq, knowing that there is a correlation between potentials and average wind speeds [23,24], then, similarly can be done for other places that are further presented through the study. The novelty brought by the work is related to the concentration of only one renewable source to cover the increasing loads since, from renewable energy sources, there is a correlation between the load during the winter and the energy production from the wind.…”
