Long-term changes in offshore wind power density and wind turbine capacity factor in the Iberian Peninsula (1900–2010)
(Elsevier, 2021-03-23)
This study analysed temporal and spatial changes in offshore wind power density (WPD) and capacity factor (CF) around the Iberian Peninsula during the 20th century by analysing data from ERA20 and ERA5. Both WPD and CF ...
The power flow and the wave energy flux at an operational wave farm: Findings from Mutriku, Bay of Biscay
(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 ...
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 ...
Performance variations of wave energy converters due to global long-term wave period change (1900–2010)
(Elsevier, 2023-04)
Long-term ocean climate effects on wave energy are often analysed from the viewpoint of the well-known increment of wave height over the decades. However, this increment associated with the increase of wave energy flux and ...
The Consequences of Air Density Variations over Northeastern Scotland for Offshore Wind Energy Potential
(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 ...
Long-Term Freezing Temperatures Frequency Change Effect on Wind Energy Gain (Eurasia and North America, 1950 & 2019)
(MDPI, 2022-05-07)
The persistent freezing conditions in cold regions are the cause of ice accretion on mechanical and instrumental elements of wind turbines. Consequently, remarkable Annual Energy Production (AEP) losses are prone to occur ...
Paradigmatic case of long-term colocated wind–wave energy index trend in Canary Islands
(Elsevier, 2023-05)
Previous studies based on remote sensing data and reanalysis have identified strong historical increments of wind speed in the area around the Canary Islands (Spain) without appreciating any increment of wave height. This ...
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 ...
