Pitch Angle Misalignment Correction Based on Benchmarking and Laser Scanner Measurement in Wind Farms
Elosegui, Unai; Egaña, Igor; Ulacia Manterola, Alain; Ibarra Berastegi, Gabriel (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 ... -
Problem-Based Learning in University Studies on Renewable Energies: Case of a Laboratory Windpump
In the last eight years, the new faculty of Engineering in Renewable Energies at the University of the Basque Country in Eibar has developed several sustainability goals related to clean energy and climate change, but also ... -
Seasonal Correction of Offshore Wind Energy Potential due to Air Density: Case of the Iberian Peninsula
Ulazia Manterola, Alain ; Ibarra Berastegi, Gabriel; Sáenz Aguirre, Jon ; Carreno Madinabeitia, Sheila; González Rojí, Santos José (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 ... -
Sensitivity Studies for a Hybrid Numerical-Statistical Short-Term Wind and Gust Forecast at Three Locations in the Basque Country (Spain)
Carreno Madinabeitia, Sheila; Ibarra Berastegi, Gabriel; Sáenz Aguirre, Jon ; Zorita, Eduardo; Ulazia Manterola, Alain (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 ... -
The Consequences of Air Density Variations over Northeastern Scotland for Offshore Wind Energy Potential
Ulazia Manterola, Alain ; Nafarrate, Ander; Ibarra Berastegi, Gabriel; Sáenz Aguirre, Jon ; Carreno Madinabeitia, Sheila (MDPI, 2019-07-09)Hywind-Scotland is a wind farm in Scotland that for many reasons is at the leading edge of technology and is located at a paradigmatic study area for offshore wind energy assessment. The objective of this paper is to compute ... -
The power flow and the wave energy flux at an operational wave farm: Findings from Mutriku, Bay of Biscay
Ibarra Berastegi, Gabriel; Ulazia Manterola, Alain ; Sáenz Aguirre, Jon ; Serras Malillos, Paula; González Rojí, Santos José; Esnaola Aldanondo, Ganix (Elservier, 2021-04-14)Mutriku is a wave farm on the Spanish coast of the Bay of Biscay that has now been continuously supplying electricity for more than nine years. Since 1979, there has been a growing trend in wave energy flux for the whole ... -
The Sailor diagram – A new diagram for the verification of two-dimensional vector data from multiple models
Sáenz Aguirre, Jon ; Carreno Madinabeitia, Sheila; Esnaola Aldanondo, Ganix; González Rojí, Santos José; Ibarra Berastegi, Gabriel; Ulazia Manterola, Alain (Copernicus Gesellschaft, 2020-07-15)A new diagram is proposed for the verification of vector quantities generated by multiple models against a set of observations. It has been designed with the objective, as in the Taylor diagram, of providing a visual ... -
Using 3DVAR data assimilation to measure offshore wind energy potential at different turbine heights in the West Mediterranean
Ulacia Manterola, Alain; Sáenz Aguirre, Jon ; Ibarra Berastegi, Gabriel; González Rojí, Santos José; Carreno Madinabeitia, Sheila (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 ...
