Query: Performance investigation on the different wave energy converters
  layouts in real wave scenarios   Wave energy is a broadly accessible renewable energy source, but principally
it is not unexploited still and fully developed. Wave energy technologies need
more investigations to reach commercial developments. In this paper, an array
of interacting wave energy converters (WECs) with various arrangements and
layout size is considered. The WEC model is a symmetrical, spherical and fully
submerged buoy with three tethers. A frequency-domain model is derived by using
linear potential theory. Numerical simulations and parametric examinations are
designed in order to evaluate the distance influence among buoys with a
pre-defined arrangement on the total power output of the array, based on the
irregular wave models. With regard to validating the best-found layout, we
perform a landscape analysis experiment using a grid search technique. These
experiments are evaluated in four real wave scenarios from south of Australia.
Experiments show that the distance between WECs and also the relative angle of
the layout to significant wave direction plays a pivotal role to harness more
power from the incident waves. Furthermore, we observe that increasing the
number of WEC in the layout leads to a rise in the optimal distance among WECs.
The maximum power of an array produced by a 5 buoy layout arrangement with 185
$m$ distance among buoys in the Tasmania wave scenario with a relative angle of
63 degrees to the significant in-site wave direction.
