Wave energy resource assessment in Menorca (Spain)

Sierra, J.P.; Mösso, C.; González-Marco, D. - In: Renewable Energy 71 (2014) C, pp. 51-60

Menorca (Balearic Islands) only covers 2% of its electricity needs with renewable energy sources, which is far below the European Union's objective of obtaining 20% of its energy from these sources. This study analyses the island's wave energy resources using a 17-year series of data obtained...

Wave energy converter control by wave prediction and dynamic programming

Li, Guang; Weiss, George; Mueller, Markus; Townley, Stuart - In: Renewable Energy 48 (2012) C, pp. 392-403

We demonstrate that deterministic sea wave prediction (DSWP) combined with constrained optimal control can dramatically improve the efficiency of sea wave energy converters (WECs), while maintaining their safe operation. We focus on a point absorber WEC employing a hydraulic/electric power...

22-Year wave energy hindcast for the China East Adjacent Seas

Liang, Bingchen; Fan, Fei; Liu, Fushun; Gao, Shanhong; … - In: Renewable Energy 71 (2014) C, pp. 200-207

In order to investigate the wave energy resource, the third-generation wave model SWAN is utilised to simulate wave parameters of the China East Adjacent Seas (CEAS) including Bohai, Yellow and East China Sea for the 22 years period ranging from 1990.1 to 2011.12. The wind parameters used to...

A linearized model for estimating the performance of submerged resonant wave energy converters

Filianoti, Pasquale; Camporeale, Sergio M. - In: Renewable Energy 33 (2008) 4, pp. 631-641

A realistic performance analysis of oscillating water column wave energy converters (WECs) addresses to a set of non-linear differential equations that need to be integrated in time, by using a stochastic approach, under the hypothesis of random wind-generated sea waves, for all the sea states...

An improved radial impulse turbine for OWC

Pereiras, Bruno; Castro, Francisco; Marjani, Abdelatif el; … - In: Renewable Energy 36 (2011) 5, pp. 1477-1484

developed with a geometry taken from the literature, but now our goal is to develop a new geometry design with a better … a new relation between their setting angles. Under sinusoidal flow conditions the new design improves the turbine … efficiency by up to 5% more than the geometry proposed by Professor Setoguchi, in 2002. In this paper, the design criteria we …

Wave farm impact: The role of farm-to-coast distance

Iglesias, G.; Carballo, R. - In: Renewable Energy 69 (2014) C, pp. 375-385

The objective of this work is to investigate how the impact of a wave farm on the nearshore wave conditions depends on its location and, more specifically, its distance to the coast. For this purpose eight case studies in an area with a very substantial wave resource are considered; they encompass...
