High Wind and Power Density Over Global Oceans
IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008Spacebased scatterometer measures ocean surface roughness, which is in equilibrium with surface stress (momentum flux). Under general conditions, the variation of stress is reflected in the variation of winds. Eight years of QuikSCAT data are used to give a good representation of the probability distribution and power density of wind speed over global ...

Evaluating Wind Power Density Models and Their Statistical Properties
Energy, 2015Abstract Information about the wind power df(density function ) is very important when measuring the wind energy potential for a specific area. Usually, the wind power df provides knowledge about the mean power, which is an indicator of the energy potential. However, the mean power does not describe well the characteristics of power density. Thus, by

Projections of wind power density in Pakistan and adjacent regions
Climate Research, 2021This work focuses on the wind energy in Pakistan projected by 3 regional climate models (RCMs), namely COSMO-CLM, REMO and RegCM4, nested in different global climate models from the Coupled Model Intercomparison Project 5. Five time-slices (1995-2014, 2020- 2039, 2040-2059, 2060-2079 and 2080-2099) and 2 scenarios (RCP2.6 and RCP8.5) were analyzed ...

Future Wind Power Scenario Synthesis Through Power Spectral Density Analysis
IEEE Transactions on Smart Grid, 2014Scenarios of near future wind power are synthesized by considering the power spectral density (PSD), statistical characteristics, and the future capacity. The PSD of the wind power follows different power laws over different frequency ranges and is approximated by a piecewise function.

Applying the Meta-heuristic Prediction Algorithm for Modeling Power Density in Wind Power Plant
2016 15th IEEE International Conference on Machine Learning and Applications (ICMLA), 2016In this paper, a robust artificial intelligence (AI) algorithm is applied to overcome challenges at power density prediction especially at the installation process of wind power plant. This algorithm also explores relationships between the meteorological parameters and power density.

Estimation of wind power density at an international airport [PDF]
Journal of energy technology, 2012 This paper deals with the development of a statistical model for the assessment of wind power density, using the wind speed data acquired at an international airport. The data were adjusted for the height at which wind power could be harvested. Wind speed data were fitted with several statistical distributions in order to determine the one that best ...

Analyzing the variability of wind power output through the power spectral density
2012 IEEE Power and Energy Society General Meeting, 2012The variability of wind power output is analyzed using the power spectral density (PSD) that is estimated through the modified covariance method, one of the parametric PSD estimation techniques. This method can estimate the PSD accurately under the assumption that the wind power follows the Autoregressive process.

Research on the Power Density of the Automatic MPPT Wind Power Generator System
2015 6th International Conference on Intelligent Systems, Modelling and Simulation, 2015Reducing the production cost is an ongoing goal for the manufacturers of small-scale off-grid wind power generator systems. However, very little research found in literature focuses on it. We proposed a novel double-winding generator in 2013 for the maximum power point tracking (MPPT) problem of the small-scale off-grid wind power generator systems ...

The Effect of Air Density Variation on Wind Power Flux
Wind Engineering, 2004Wind energy potential is proportional to both air density and the third power of the wind speed averaged over a suitable time period. The wind speed and air density are random variables depending on both time and location. The main objective of this paper is to derive a general wind energy potential formulation, considering the time dependence of both

Power spectral densities of zonal and meridional winds in the stratosphere
Physica Scripta, 1988In a previous publication [1], we described the power spectral densities (PSD's) of very high resolution (10 m) scalar winds in the stratosphere based on the triangulated, rocket-laid smoke trail method. The PSD's were obtained there by means of a fast fourier transform version of the Blackman-Tukey technique [2].
