Effect of Air Density on Output Power of Wind Turbine

Applied Mechanics and Materials, 2013
This paper elaborates the effect of wind speed on the output power of the wind farms at different locations. It also describes the correction of the power curve and shows the comparison chart of the standard power curve and the power curve after correction.

On the Vertical Extrapolation of Mean Wind Power Density

Journal of Applied Meteorology, 1980
Abstract A simple method of estimating the height variation of the mean wind power density is presented which accounts for the variation of the exponent p of the wind speed power law, with stability and roughness. Measurements are used to compare the new method to two previously suggested methods.

THE DENSITY FLUCTUATION POWER SPECTRUM OF THE INNER SOLAR WIND

1992
ABSTRACT Recent work has been done at Arecibo and UCSD to arrive at a self-consistent model of the density fluctuation power spectrum inside 25 Rs based on a comparison of spectral broadening, angular broadening, intensity scintillation, and phase scintillation measurements.

Power spectrum of density irregularities in the solar wind plasma

Journal of Geophysical Research, 1973
Observations of interplanetary scintillations are compared with predictions based on a spatial electron density spectrum extrapolated from the power law shape at wave numbers 10−6–10−5 rad/km measured from spacecraft. The influences of the power law exponent, a high wave number cutoff, and the Fresnel filter are examined with respect to scintillation ...

Four-Parameter Models for Wind Farm Power Curves and Power Probability Density Functions

IEEE Transactions on Sustainable Energy, 2017
This letter is an additional contribution to the calculation of wind farm power curves and power probability density functions with the help of the logistic function and Jensen’s model for wake effect calculation. The goal is to complete a previous formulation based on the use of the 3P-DP logistic function, with two other, called the 4P-DS and the 4P ...

Probability Density Function and Prediction of Wind Power Variations

Journal of Information and Computational Science, 2014
Variation is an intrinsic property of wind power. It has been proved that generalized Pareto distribution is suitable to identify the probability distribution of wind power variations after mass field measurements. And analysis shows that distribution of wind power is leptokurtic and rightward skewed.

The probability density distribution for the power output from arrays of wind turbines and the intermittent nature of wind power

Journal of Wind Engineering and Industrial Aerodynamics, 2013
Abstract This paper discusses the probability density distribution of the power output from arrays of turbines distributed over different geographical areas. Based on a model of a square array of turbines, estimates are obtained for the reduction in the standard deviation of the power output from the turbine arrays as a function of the area of the ...
