Abstract
Incorporating the non-ideal power take-off (PTO) efficiency of wave energy converters (WECs) into energy-maximizing
control is crucial for achieving optimal electrical power generation.
The majority of previous loss-aware controllers are based on a
simplified power-coefficient (PC) model or only consider the copper
loss, which remain insufficient to describe a real electrical PTO. In
this article, a high-fidelity loss model, encompassing different loss
components of the PTO (a generator and a power converter), is
developed, and a number of loss-aware model predictive control
(MPC) options are derived and compared in a realistic case study.
The results highlight the importance of using an appropriate loss
model, rather than a PC model, both for power evaluation and
for control, and it is shown that a quadratic loss model employed
in MPC is effective in approximating the true loss function, so
that near-optimal power production can be achieved with fast
computation.
