The influence of different wind and wave conditions on the energy yield and downtime of a Spar-buoy floating wind turbine
(2019-06)
Article
Accés restringit per política de l'editorialFloating offshore wind turbines (FOWT) have been extensively proven in model tests and are reaching currently a pre-commercial phase where large scale demonstrators are being built offshore. This transition increases the ... -
Solar vanadium redox-flow battery powered by thin-film silicon photovoltaics for efficient photoelectrochemical energy storage
(Institute of Physics (IOP), 2018-11-15)
Article
Accés obertSolar-powered vanadium redox-flow batteries (VRFB) have emerged as an attractive method for large-scale and efficient energy storage and conversion. However, due to the stringent charging voltage requirements of vanadium-based ... -
A wind farm control strategy for power reserve maximization
(Elsevier, 2019-02-01)
Article
Accés obertNowadays, in many countries wind energy is responsible for a significant part of the electricity generation. For this reason, Transmission System Operators (TSOs) are now demanding the wind power plants (WPPs) to contribute ... -
P-type c-Si solar cells based on rear side laser processing of Al 2O 3/SiC x stacks
(2012-11)
Article
