Impact of local meteorological parameters on wind characteristics in specific recording conditions — High altitude wind speed in transient climate zones

Intermittent renewable generation plays a significant role in power system planning, hence the requirement for more exact data and resource representation for power system modeling is of high interest. It is therefore the aim of this paper to analyze properties of the wind resource in specific operating conditions. As Bosnia-Herzegovina (B&H) abounds with mountain plateaus at high altitudes, the paper will analyze data records of four recording sites located at altitudes ranging from 1250m to 1700m a.s.l. Due to the specific geographic position and topography, the country experiences different climate conditions (Mediterranean, Moderate Continental and Alpine Climate) within a rather small surface area, which also has an effect at the recording sites of interest. The rate of change of diurnal patterns by season is analyzed by means of the Normalized Root-Mean-Square deviation (NRMS), whereby occurrence and intensity of occurring patterns is analyzed by means of the Fast Fourier Transform (FFT). The paper finds interesting results on wind statistics and the related operating conditions, with particular focus on mean diurnal wind profile and variability and the rate of change by season.
