Pitch Angle Misalignment Correction Based on Benchmarking and Laser Scanner Measurement in Wind Farms
(MDPI, 2018-12-01)
In addition to human error, manufacturing tolerances for blades and hubs cause pitch angle misalignment in wind turbines. As a consequence, a significant number of turbines used by existing wind farms experience power ...
Downscaling of surface moisture flux and precipitation in the Ebro Valley (Spain) using analogues and analogues followed by random forests and multiple linear regression
(Copernicus Gesellschaft, 2011)
In this paper, reanalysis fields from the ECMWF have been statistically downscaled to predict from large-scale atmospheric fields, surface moisture flux and daily precipitation at two observatories (Zaragoza and Tortosa, ...
Historical Evolution of theWave Resource and Energy Production off the Chilean Coast over the 20th Century
(MDPI, 2018-09)
The wave energy resource in the Chilean coast shows particularly profitable characteristics for wave energy production, with relatively high mean wave power and low inter-annual resource variability. This combination is ...
Harmonized evaluation of daily precipitation downscaled using SDSM and WRF+WRFDA models over the Iberian Peninsula
(Springer, 2019-08)
There have been numerous statistical and dynamical downscaling model comparisons. However, differences in model skill can be distorted by inconsistencies in experimental set-up, inputs and output format. This paper harmonizes ...
MIDAS: A Benchmarking Multi-Criteria Method for the Identification of Defective Anemometers in Wind Farms
(MDPI, 2018-12-22)
A novel multi-criteria methodology for the identification of defective anemometers is shown in this paper with a benchmarking approach: it is called MIDAS: multi-technique identification of defective anemometers. The ...
Electricity production, capacity factor, and plant efficiency index at the Mutriku wave farm (2014–2016)
(Elsevier, 2018-01-01)
Mutriku has recently become the first commercial wave farm to release its operating data. The plant has 14 OWC operating turbines, and this study has conducted an analysis of hourly data corresponding to the 2014–2016 ...
Using 3DVAR data assimilation to measure offshore wind energy potential at different turbine heights in the West Mediterranean
(Elsevier, 2017-09-19)
In this article, offshore wind energy potential is measured around the Iberian Mediterranean coast and the Balearic Islands using the WRF meteorological model without 3DVAR data assimilation (the N simulation) and with ...
Analysis of atmospheric thermodynamics using the R package aiRthermo
(Elsevier, 2018-10-23)
The publicly available R package aiRthermo is presented in this study, which allows the user to process information relative to atmospheric thermodynamics, ranging from calculating the density of dry or moist air and ...
Sensitivity Studies for a Hybrid Numerical-Statistical Short-Term Wind and Gust Forecast at Three Locations in the Basque Country (Spain)
(MDPI, 2019-12-29)
This study evaluates the performance of statistical models applied to the output of numerical models for short-term (1–24 h) hourly wind forecasts at three locations in the Basque Country. The target variables are horizontal ...
Seasonal Correction of Offshore Wind Energy Potential due to Air Density: Case of the Iberian Peninsula
(MDPI, 2019-07-02)
A constant value of air density based on its annual average value at a given location is commonly used for the computation of the annual energy production in wind industry. Thus, the correction required in the estimation ...
