Abstract
The magnitude of energy, which is extracted by tidal energy converter
devices, has a significant impact on the commercial viability of
an entire project. Therefore a substantialcharacterization of the
tidal current at the location of interest and subsequently a confident
prediction of the electricity production of the tidal energy converter
at an early stage of the project is of high interest. This paper
deals with a method to estimate the production of a single device
using results from a 2D shallow water equation model combined with
turbine performance curves and its validation by performance data
from operations of the Voith prototype HyTide 110-5.3 under real
conditions in Jindo, South Korea. A recently developed 2D shallow
water equation solver based on OpenFOAM (tidalFoam) is used to accurately
simulate the tidal current around the installation location of the
device.High-resolved bathymetry data, shorelines and tidal elevation
at the open boundaries of the unstructured mesh is used to set up
the model. The bottom friction as an additional implicit source term
in the model is used to calibrate the simulation against Acoustic
Doppler Current Profiler (ADCP) measurements at site. The expected
electricity production is compared with actual field measurements
during the operation of the Voith scaled demonstrator. The complete
analysis and results gives valuable and significant confidence in
the performance expectation of the single tidal turbine. The results
show that the production of single devices can be accurately estimated.
This grants an important first input to commercial evaluations of
future tidal energy projects.
