Abstract: |
Electrical power cables in tidal turbine farms
contribute a significant share to capital expenditure
(CAPEX). As a result, the routing of electrical power
cables connecting turbines to cable collector hubs must be
designed so as to obtain the least cost configuration. This is
referred to as a tidal cable routing problem. This problem
possesses several variants depending on the number of
cable collector hubs. In this paper, these variants are
modeled by employing the approach of the single depot
multiple traveling salesman problem (mTSP) and the
multiple depot mTSP of operational research for the single
and multiple cable collector variants, respectively. The
developed optimization models are computationally
implemented using MATLAB. In the triple cable collector
cable hub variant, an optimal solution is obtained, while
good-quality suboptimal solutions are obtained in the
double and single cable collector hub variants. In practice,
multiple cable collector hubs are expected to be employed
as the multiple hub configurations tend to be more economic
than the single hub configurations. This has been
confirmed by this paper for an optimal tidal turbine layout
obtained with OpenTidalFarm. Suggestions are presented
for future research studies comprising a number of
heuristics. |
