How does wind speed distribution affect wind energy output estimation?
The wind speed distribution at a specific location determines the available wind energy and the performance of the energy conversion system. Therefore, to reduce the uncertainty of wind energy output estimation, it is necessary to accurately understand the distribution characteristics of wind speed (Celik, 2003).
What are the characteristics of wind speed distribution?
The characteristics of wind speed distribution are constantly varying geographically and temporally. Wind energy assessment should consider local geographical elements, such as local climate, topography, and thermal properties difference between the land and the sea, and focus on long-term variations in wind characteristics.
How do we assess wind energy potential?
There are many wind energy potential analyses, ranging from regional scales (e.g., McKenna et al., 2013) to the scale of the whole world (e.g., Lu et al., 2009) which assess the wind energy potential in a spatially explicit manner, so that for each spatial unit of the study region the wind energy potential can be identified.
How reliable is extreme wind speed distribution?
However, due to the lack of historical extreme wind speed data, the traditional extreme value distribution can only estimate the annual maximum wind speed distribution and does not consider the monthly or daily extreme winds, thus reducing the reliability of quantifying extreme events (Torrielli et al., 2013).
How accurate is Weibull distribution in estimating wind power output?
The three-parameter Weibull distribution can estimate the probability of null wind speed and give greater weight to low wind speeds. Wais (2017b) showed that the accuracy of the two-parameter Weibull distribution is higher in estimating wind power output only when the null wind speed is insignificant.
What are the different types of wind speed distribution models?
Several probability distribution models have been widely used in wind farm analysis, planning, design, construction, and operation. Wind speed distribution models can be roughly divided into two classes: parametric distribution models and nonparametric distribution models.
