In this paper, we propose a novel technique to determine the optimal placement of wind farms, thereby taking into account wind characteristics and electrical grid constraints. We model the long-term variability of wind speed using a Weibull distribution according to wind direction intervals, and formulate the metrics that capture wind speed characteristics at a specific location, namely the ari...

Swifts regularly spend the night flying at high altitude. From previous studies based on tracking radar observations, we know that they stay airborne during the night and prefer to orient themselves into the wind direction with an increased angular concentration with increasing wind speed. In this study, we investigated the orientation relative to the wind of individual swifts by frequency (dis...

This paper presents a new method to accurately characterize and predict the annual variation of wind conditions. Estimation of the distribution of wind conditions is necessary (i) to quantify the available energy (power density) at a site, and (ii) to design optimal wind farm configurations. We develop a smooth multivariate wind distribution model that captures the coupled variation of wind spe...

A new maximum power extraction (MPE) controller for variable speed permanent magnet synchronous generator (PMSG) wind energy conversion systems (WECS) is proposed. The proposed controller generates optimum speed reference signal for the speed control loop of the vector controlled machine side converter control system without requiring the knowledge of wind speed using only active power and air ...

The physics of remote sensing sea surface measurements is still poorly understood under severe weather conditions. Wind vector algorithms are usually developed for non-precipitating atmospheres and for wind speeds less than 20 m/s. In this study, we analyze observations from the QuikSCAT Kuband scatterometer collocated with the WindSat full polarimetric microwave radiometer to estimate the pote...

wind erosion climatic factor is a measure of climatic factors explaining the wind erosion erosivity. humidity and wind speed are climatic characteristics that must be considered as the erosion parameters. in this study, linear moment analysis (l-moments) and wind erosion climatic factor were used to evaluate the regional climate’s tendency effect on wind erosion in yazd province. wind erosion c...
