“…Wave energy resource assessments have been an important factor for wave energy developments in recent years, and the focus has been on the assessment and characterisation of wave energy resources [1][2][3][4][5][6][7][8][9][10][11][12][13], with the global wave energy resource assessments on the overall resources and the distributions of wave energy [3][4][5][6], and the regional and national wave energy resources on the potentials for developing wave energy [7][8][9][10][11][12][13]. As pointed out by Cahill et al [7], the primary purpose of these studies is to examine the available potential energy at the locations of interest, and of the seasonal and annual trends in the resources.…”

A Method for Energy and Resource Assessment of Waves in Finite Water Depths

This paper presents a new method for improving the assessment of energy and resources of waves in the cases of finite water depths in which the historical and some ongoing sea wave measurements are simply given in forms of scatter diagrams or the forms of (significant) wave heights and the relevant statistical wave periods, whilst the detailed spectrum information has been discarded, thus no longer available for the purpose of analysis. As a result of such simplified wave data, the assessment for embracing the effects of water depths on wave energy and resources becomes either difficult or inaccurate. In many practical cases, the effects of water depths are simply ignored because the formulas for deep-water waves are frequently employed. This simplification may cause large energy under-estimations for the sea waves in finite water depths. To improve the wave energy assessment for such much-simplified wave data, an approximate method is proposed for approximating the effect of water depth in this research, for which the wave energy period or the calculated peak period can be taken as the reference period for implementing the approximation. The examples for both theoretical and measured spectra show that the proposed method can significantly reduce the errors on wave energy assessment due to the approximations and inclusions of the effects of finite water depths.

“…Kim et al [14] assessed the wave energy in offshore deep waters in the sea areas adjacent to Korea based on a hindcast dataset from 1979 to 2003 and evaluated the wave energy in the relatively nearshore waters of Hongdo by using the SWAN model. From 2009 to 2011, Iglesias et al [15][16][17][18][19][20] conducted a refined evaluation of several small-scale areas in the sea areas adjacent to Spain based on wave model data. Liang et al [21] assessed the wave energy for two important areas in the adjacent seas to the east of China based with 22 years of wave data by using the SWAN model.…”

Wave Energy Resource Assessment off the Coast of China around the Zhoushan Islands

et al. 2017

Based on ERA-Interim reanalysis wave field data for the 36 years from 1979 to 2014, the temporal and spatial distributions and development potential of wave energy are studied in detail in the offshore and relatively nearshore waters adjacent to the Zhoushan Islands. The results show that areas of relatively high wave energy are located in the offshore waters to the east and southeast of the Zhoushan Islands. The potential wave energy in relatively nearshore waters (water depths from 10 m to 65 m) is relatively higher and especially in the nearshore waters to the southeast of the city of Taizhou, Zhejiang Province, which are suitable locations for wave energy development. The conclusions provide scientific guidance for wave energy development in the sea areas adjacent to the Zhoushan Islands.

“…The efforts of several research groups were oriented toward the determination of the most attractive sites and of the most reliable technologies for wave energy exploitation. The former analyses were conducted in several areas, such as the Mediterranean Sea [3][4][5][6][7][8][9], the Black Sea [10,11], the USA [12][13][14] and in various Asian regions [15][16][17]. The latter analyses involved the conception of a variety of devices and theoretical and experimental tests on both small-scale and full-scale devices [18][19][20].…”

Estimation of Downtime and of Missed Energy Associated with a Wave Energy Converter by the Equivalent Power Storm Model

et al. 2015

View full text Add to dashboard Cite

Abstract:The design of any wave energy converter involves the determination of relevant statistical data on the wave energy resource oriented to the evaluation of the structural reliability and energy performance of the device. Currently, limited discussions concern the estimation of parameters connected to the energy performance of a device. Thus, this paper proposes a methodology for determining average downtime and average missed energy, which is the energy that is not harvested because of device deactivations during severe sea storms. These quantities are fundamental for evaluating the expected inactivity of a device during a year or during its lifetime and are relevant for assessing the effectiveness of a device working at a certain site. For this purpose, the equivalent power storm method is used for their derivation, starting from concepts pertaining to long-term statistical analysis. The paper shows that the proposed solutions provide reliable estimations via comparison with results obtained by processing long wave data.
