Extension and improvement of synchronous linear generator based point absorber operation in high wave excitation scenarios
(Elsevier, 2021-11-01)
[EN]The exploitation of marine wave energy resource has led to the design of numerous Wave Energy Converter (WEC) configurations. The power absorption of a WEC is tightly related to its physical properties and the ...
The Sailor diagram – A new diagram for the verification of two-dimensional vector data from multiple models
(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 ...
Optimal strategies of deployment of far offshore co-located wind-wave energy farms
(Elsevier, 2022-01-01)
[EN] The most profitable offshore energy resources are usually found away from the coast. Nevertheless, the accessibility and grid integration in those areas are more complicated. To avoid this problematic, large scale ...
Combining random forests and physics-based models to forecast the electricity generated by ocean waves: A case study of the Mutriku wave farm
(Pergamon-Elsevier, 2019-10-01)
This paper combines random forests with physics-based models to forecast the electricity output of the Mutriku wave farm on the Bay of Biscay. The period analysed was 2014-2016, and the forecast horizon was 24 h in 4-h ...
Global estimations of wind energy potential considering seasonal air density changes
(Pergamon-Elsevier, 2019-11-15)
The literature typically considers constant annual average air density when computing the wind energy potential of a given location. In this work, the recent reanalysis ERA5 is used to obtain global seasonal estimates of ...
Problem-Based Learning in University Studies on Renewable Energies: Case of a Laboratory Windpump
(MDPI, 2020-03-23)
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 ...
Floating wind turbine energy and fatigue loads estimation according to climate period scaled wind and waves
(Elsevier, 2022-11)
Offshore wind power is one of the fastest-growing renewable energy sources, as it is expected to play a major role in the transition towards sustainability and net zero emissions. Despite its potential, the interaction of ...
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 ...
CMIP6 projections for global offshore wind and wave energy production (2015–2100)
(Nature, 2023-10)
Three-hourly CMIP6 projections have been used in conjuction with the CSIRO WaveWatchIII wave model to calculate the global trends in offshore wind and wave energy for the SSP585 and SSP126 scenarios until 2100. The results ...
Performance enhancement of the artificial neural network– based reinforcement learning for wind turbine yaw control
(Wiley, 2019-11-03)
The yaw angle control of a wind turbine allows maximization of the power absorbed
from the wind and, thus, the increment of the system efficiency. Conventionally, classical
control algorithms have been used for the yaw ...
