The main objective of the study is to assess the historical and near future efficiency and energy cost of two WECs (Aqua Buoy and Pelamis). A SWAN model was used to downscale the wave parameters along the NW coast of the Iberian Peninsula both for a historical period (1979–2005) and the near future (2026–2045) under the RCP 8.5 greenhouse scenario. The past and future efficiency of both WECs were computed in terms of two parameters that capture the relationship between sea states and the WEC power matrices: the load factor and the capture width. -

Abstract B. Introduction This study examines the novel concept of extracting wave The extraction of energy from ocean waves possesses immense energy at Helmholtz resonance. The device includes a basin with potential, and with the growing global energy crisis and the need to develop alternative, reliable and environmentally non-detrimental horizontal cross-sectional area A0 that is connected to the sea by a channel of width B and length L, where the maximum water sources of electricity, it’s crucial that we learn to exploit it. depth is H. The geometry of the device causes an oscillating fluid within the channel with the Helmholtz frequency of Beginning in early 19th century France, the idea of harvesting 2 σH =gHB/A0L while the strait's length L, as well as the basin's the ocean’s energy has grown to become a great frontier of the 1/2 length scale A0 , are much smaller than the incoming wave's energy industry. Myriad methods of extraction have arisen, notable wavelength. In this article, we examined the relation of above among them Scotland’s Pelamis Wave Energy Converter [1], Oyster th th frequency to the device’s geometry in both 1/25 and 1/7 [2], Sweden’s Lysekil Project [3], Duck wave energy converter [4], scaled models at wave tank. -

The waves of major concern to a harbor engineer are generated by the action of wind. The wind creates a disturbance in the sea which is restored to its calm equilibrium position by the action of gravity and hence resulting waves are called wind generated gravity waves. -

It has declared itself to become the wind power capital of Finland. The aim of this paper is to find out what being a wind power capital can mean in practice and how it can advance the local industrial business. First, the theoretical framework of this systematic review study was formed by searching theoretical information about the forms of industrial clusters, and it was then examined what kinds of actors take part in these types of clusters. -
Comparative Study of Wind Turbine Placement Methods for Flat Wind Farm Layout Optimization with Irregular Boundary
applied sciences Article Comparative Study of Wind Turbine Placement Methods for Flat Wind Farm Layout Optimization with Irregular Boundary Longyan Wang 1,2,3 1 Research Center of Fluid Machinery Engineering and Technology, Jiangsu University, Zhenjiang 212013, China; [email protected] 2 School of Chemistry, Physics and Mechanical Engineering, Queensland University of Technology, Brisbane 4001, Australia 3 Department of Mechanical Engineering, University of Alberta, Edmonton, AB T6G 2R3, Canada Received: 18 December 2018; Accepted: 11 February 2019; Published: 14 February 2019 Featured Application: The comparative results of the effectiveness of different wind turbine placement methods will facilitate the application of a more advantageous method to be used for the wind farm design, and hence improve the cost effectiveness of wind power exploitation. Abstract: For the exploitation of wind energy, planning/designing a wind farm plays a crucial role in the development of wind farm project, which must be implemented at an early stage, and has a vast influence on the stages of operation and control for wind farm development. As a step of the wind farm planning/designing, optimizing the wind turbine placements is an effective tool in increasing the power production of a wind farm leading to an increased financial return. In this paper, the optimization of an offshore wind farm with an irregular boundary is carried out to investigate the effectiveness of grid and coordinate wind farm design methods. In the study of the grid method, the effect of grid density on the layout optimization results is explored with 20 × 30 and 40 × 60 grid cells, and the means of coping with the irregular wind farm boundary using different wind farm design methods are developed in this paper.
