Most of the referenced papers have been published during the last five years, although older key references have also been included for consistency. The focus of the paper is on the state of the art in this research field.

Further, the paper aims to outline possible routes on how to reach that goal. The paper poses questions on how realistic the current models and results for wave energy park optimization are, how reliable they are, and if they are relevant.
The aim of the current paper is to ask how far we are from providing such answers. In short, the goal of the research should be to provide wave energy developers with clear, unbiased and reliable answers on how they should best design their park, given the constraints they are facing. Ideally, optimization of a wave energy park should find the best available solution to an objective function that considers all aspects of the park, including all costs and total revenue over the lifetime, reliability, constraints regarding available ocean area, deployment, and maintenance, allowed power fluctuations, water depth, etc. In recent years, there has been a vast increase in the research field of wave energy park optimization, and several global optimization algorithms have been developed and applied. Many papers on wave energy parks have claimed to carry out optimization, whereas, in reality, they have only compared a few distinct configurations or tuned one parameter to obtain a minimum or maximum point. In a more complex situation, optimization includes finding the best available values of some objective functions given a defined parameter space. In the simplest case, an optimization problem consists of maximizing or minimizing a real function by systematically choosing input values from an allowed set and computing the value of the function. Optimization is the procedure of identifying the best solution from some set of available alternatives, under given constraints. Wave climate, wave direction and variability, water depth, currents, and distance from shore are some factors that all affect the wave energy system, and different sites and environmental conditions will require different optimal solutions. In addition, environmental parameters have a large impact on the park. The number of devices and their separation distance, the park layout, mooring configurations, electrical and power take-off (PTO) systems, rated power of individual devices, constraints of subsystems, and so on-all parameters should be tuned to obtain the optimal design of the wave energy park before installation. As a result, many parameters will affect the interaction and the park performance, reliability, and costs. The interaction can be hydrodynamical (scattered and radiated waves), mechanical (shared mooring and foundations), electrical (sea cables, substations, grid connection), and economic (shared capital and operational costs).

Interaction between the devices will affect the full performance, reliability, cost, and life-time of the park. To produce electricity in the range above a few MW, most wave energy concepts require that wave energy converters (WECs) are deployed together in arrays, or parks. Since virtually everything we do in this course deals with three dimensional space, it makes sense to start with a short discussion of how to represent a point in 3-D space.Wave energy has the potential to contribute significantly to the world's electricity consumption.
