Successful development of Wave Energy Conversion
technology is made difficult by a combination of
factors, these include; the inaccessible nature of the
target ocean locations; the relatively high cost of
fullscale device testing; the stochastic nature of
ocean waves; the strong interaction between subsystem
designs; and, the apparent gulf between
required and, so far, demonstrated performance.
These difficulties taken together mean that design
optimisation in software should assume a greater
importance in wave energy than it does in other
industries at comparable maturity.
This paper presents a techno-economic optimisation
of a generic wave energy converter, namely a hinged
barge. The optimisation is techno-economic in the
sense that the optimisation algorithm manipulates
the technical parameters of the device in order to
improve the value of an economic objective
function. The economic objective function used is
the estimated net present value of a large array
deployment. The technical parameters included are
device geometry, power transmission equipment
design and control parameters. A comparison
between the techno-economic optimisation and an
optimisation using a purely technical objective
function is presented. The results show that the
techno-economic optimisation results in a superior
economic performance and significantly different
optimised designs.
