Short term prediction of wind speed based on long-short term memory networks [PDF]

open access: yesFME Transactions, 2021
Power utilities, developers, and investors are pushing towards larger penetrations of wind and solar energy-based power generation in their existing energy mix. This study, specifically, looks towards wind power deployment in Saudi Arabia. For profitable

Reconstruction of Helio-latitudinal Structure of the Solar Wind Proton Speed and Density [PDF]

open access: yes, 2015
The modeling of the heliosphere requires continuous three-dimensional solar wind data. The in-situ out-of-ecliptic measurements are very rare, so that other methods of solar wind detection are needed.

Influence of Initial Conditions on Wind Characteristics at a Bridge Middle Span in a U-Shaped Valley by CFD and AHP

open access: yesApplied Sciences, 2022
The wind parameter distribution law at a bridge midspan in a U-shaped valley has important influence on the wind strength of this bridges. In this paper, the wind characteristics were researched by computational fluid dynamics (CFD).

A spliced Gamma-Generalized Pareto model for short-term extreme wind speed probabilistic forecasting [PDF]

open access: yes, 2019
Renewable sources of energy such as wind power have become a sustainable alternative to fossil fuel-based energy. However, the uncertainty and fluctuation of the wind speed derived from its intermittent nature bring a great threat to the wind power ...

Research on neural network wind speed prediction model based on improved sparrow algorithm optimization

open access: yesEnergy Reports, 2022
The wind speed signal measured by the mechanical anemometer lags behind the wind speed at the wind wheel surface of the wind turbine in time. The wind speed reconstruction algorithm adopted by the ordinary lidar anemometer is insufficient.

A multifractal description of wind speed records [PDF]

open access: yesChaos, Solitons & Fractals, 2005
In this paper, a systematic analysis of hourly wind speed data obtained from four potential wind generation sites in North Dakota is conducted. The power spectra of the data exhibited a power law decay characteristic of $1/f^ $ processes with possible long range correlations.

Wind turbine condition assessment through power curve copula modeling [PDF]

open access: yes, 2012
Power curves constructed from wind speed and active power output measurements provide an established method of analyzing wind turbine performance. In this paper it is proposed that operational data from wind turbines are used to estimate bivariate ...
