Wind Speed Prediction via Collaborative Filtering on Virtual Edge Expanding Graphs

open access: yesMathematics, 2022
Accurate and stable wind speed prediction is crucial for the safe operation of large-scale wind power grid connections. Existing methods are typically limited to a certain fixed area when learning the information of the wind speed sequence, which cannot ...

A Novel Statistical Method to Temporally Downscale Wind Speed Weibull Distribution Using Scaling Property

open access: yesEnergies, 2018
To improve our capacity to use available wind speed data, it is necessary to develop a new statistical temporal downscaling method that uses one or a few input variables of any temporal scale for mean wind speed data to obtain wind statistics at finer ...

Wind Characteristics in the Taiwan Strait: A Case Study of the First Offshore Wind Farm in Taiwan

open access: yesEnergies, 2020
This study analyzed the wind speed data of the met mast in the first commercial-scale offshore wind farm of Taiwan from May 2017 to April 2018. The mean wind speed and standard deviation, wind rose, histogram, wind speed profile, and diurnal variation of

Complexity Analysis of Wind Energy, Wind Speed and Wind Direction in the light of nonlinear technique [PDF]

open access: yesarXiv, 2022
Wind energy has an inherent intermittent character due to certain inevitable factors of nature, such as availability of wind at different weather conditions, wind direction etc. To study the intermittent character of wind energy, its daily data along with the two other important quantities, wind speed and wind direction measured in a "showcase" wind ...

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 New High-Dimensional Time Series Approach for Wind Speed, Wind Direction and Air Pressure Forecasting [PDF]

open access: yesEnergy, Volume 135, 15 September 2017, pp 833--850, 2017
Many wind speed forecasting approaches have been proposed in literature. In this paper a new statistical approach for jointly predicting wind speed, wind direction and air pressure is introduced. The wind direction and the air pressure are important to extend the forecasting accuracy of wind speed forecasts. A good forecast for the wind direction helps
