Variability assessment and forecasting of renewables: A review for solar, wind, wave and tidal resources

Widén, Joakim; Carpman, Nicole; Castellucci, Valeria; … - In: Renewable and Sustainable Energy Reviews 44 (2015) C, pp. 356-375

Integrating variable and non-dispatchable renewable power generation into existing power systems will have consequences for their operation and future expansion. These impacts will depend on two factors: (1) the variability of the total renewable power generation on different time scales and (2)...

Wave energy resource in the Estaca de Bares area (Spain)

Iglesias, G.; Carballo, R. - In: Renewable Energy 35 (2010) 7, pp. 1574-1584

The area around Cape Estaca de Bares (the northernmost point of Iberia) presents a great potential for wave energy exploitation owing to its prominent position, with average deepwater wave power values exceeding 40kW/m. The newly available SIMAR-44 dataset, composed of hindcast data spanning 44...

Wave energy resources: Wave climate and exploitation

Portilla, Jesus; Sosa, Jeison; Cavaleri, Luigi - In: Renewable Energy 57 (2013) C, pp. 594-605

In identifying the most convenient zones for harvesting wave energy, it is natural to be attracted by the areas where we find the highest mean energy values. The obvious examples are the storm belts. A more careful analysis reveals that for practical use other factors need to be taken into...

The role of tides in shelf-scale simulations of the wave energy resource

Hashemi, M. Reza; Neill, Simon P. - In: Renewable Energy 69 (2014) C, pp. 300-310

Many regions throughout the world that are suitable for exploitation of the wave energy resource also experience large tidal ranges and associated strong tidal flows. However, tidal effects are not included in the majority of modelling studies which quantify the wave energy resource. This...

An experimental study on the efficiency of the submerged plate wave energy converter

Orer, G.; Ozdamar, A. - In: Renewable Energy 32 (2007) 8, pp. 1317-1327

Several studies have been made using submerged plates for wave-damping purpose. A pulsating flow occurs opposite to the direction of wave propagation below these wave breakers. This water flow can be used for energy production purposes. In this study, the energy efficiency of the plate wave...

Wave energy potential along the Death Coast (Spain)

Iglesias, G.; Carballo, R. - In: Energy 34 (2009) 11, pp. 1963-1975

The newly available SIMAR-44 data set, covering a 44-year period, is used together with wave buoy data to assess the wave energy resource along the Death Coast, the craggy stretch from Cape Finisterre to the Sisarga Isles. Its location at the north-western corner of the Iberian Peninsula and its...

Offshore and inshore wave energy assessment: Asturias (N Spain)

Iglesias, G.; Carballo, R. - In: Energy 35 (2010) 5, pp. 1964-1972

The offshore and inshore wave energy resource in Asturias (N Spain) is studied using wave buoy data and a hindcast dataset spanning 44 years (1958–2001). Offshore average wave power and annual wave energy values are found to exceed 30 kW/m and 250 MWh/m, respectively, at 7 of the 11 study...
