“…Depending on the relative position of the devices and the angle of incidence of the waves, however, strong destructive effects can also arise, deteriorating the performance of the system. Concerning interactions between multiple devices of different types, a comprehensive review on the state of the art of wave energy park modelling has been recently presented by Göteman et al [55].…”

We review wave energy conversion technologies for niche applications, i.e., kilowatt-scale systems that allow for more agile design, faster deployment and easier operation than utility scale systems. The wave energy converters for niche markets analysed in this paper are classified into breakwater-integrated, hybrid, devices for special applications. We show that niche markets are emerging as a very vibrant landscape, with several such technologies having now achieved operational stage, and others undergoing full-scale sea trials. This review also includes flexible devices, which started as niche applications in the 1980s and are now close to commercial maturity. We discuss the strong potential of flexible devices in reducing costs and improving survivability and reliability of wave energy systems. Finally, we show that the use of WECs in niche applications is supporting the development of utility-scale projects by accumulating field experience, demonstrating success stories of grid integration and building confidence for stakeholders.

“…As an example, linearized potential flow take all three of them into account. According to [53,54], the most common numerical method for hydrodynamic modeling is Boundary element method (BEM) allowing to numerically solve the motions of WECs having different geometry and shape, with full consideration of wave interactions between bodies [4]. Regarding to BEM solvers, WAMIT is one of the many software for determining the interactions between offshore devices and wave.…”

“…Also the master configuration is different in each study. Although in Göteman review paper [53] layout trends are likely to be aligned perpendicular to the direction o predominant wave, it is worth to mention the wedge (arrow) shape and staggered layouts in regular pattern without using optimization methods to return worthful outputs. Finally, using optimization is an alternative choice because it searches all the possible solutions so the results become more viable and secure, and an increase in the number of publications about layout optimizations confirms this.…”

Ocean wave energy is one of the latest renewable energy resources, projected to be commercialized and competitive with other energy technologies in the near future. However, wave energy technologies are not fully developed, so various criteria must be optimized to enter the energy market. To optimize the performance of wave energy converters (WECs) components, three challenges are mostly considered: i)Power take-off systems settings (PTO), ii)Geometry parameters of WECs, iii)WECs' layout. As each of them plays a significant role in harnessing the maximum power output, this paper reviews applied optimization techniques in WECs. Furthermore, due to the importance of fidelity and computational cost in numerical methods, we discuss methods to analyze a WEC together with the basics and developments of WECs interactions. Moreover, the most popular optimization methods applied to optimize WEC parameters are categorized, and their key characteristics are briefly discussed. As a result, in terms of convergence rate, a combination of bio-inspired algorithms and local search can outperform the competition in layout optimization. A review of PTO coefficients and the geometry of WECs have emphasized the indispensability of optimizing PTO coefficients and

“…Up to now, various optimization methods and relevant processes have been developed and utilized by various researchers for the case of isolated (i.e., without the presence of the wall) arrays [20]. Child and Venupogal [21] studied the effect of the spatial configuration of WECs arrays in terms of the total absorbed power by coupling an analytical hydrodynamic model with two different optimization methods; the parabolic intersection method and the Genetic Algorithms (GAs).…”
