“…Therefore, to afford the greatest chance of success to the present study, the tidal hydrodynamic model of energy extraction within DTOcean is revisited and improved, as detailed in the next section. Beyond the calibrations mentioned in Section 3, the remainder of the DTOcean suite is unchanged from the model applied in [25].…”

“…Given the importance of accurate calculation of annual energy production (AEP) to LCOE estimates, it is prudent to address the advantages and limitations of the tidal hydrodynamics solver contained within DTOcean. This section expands upon the description given in [25], utilises details from [28], and builds upon the previous methodology. The key output of the algorithm described in this section is the mean mechanical annual energy production (MMAEP), the AEP without losses due to transmission or maintenance downtime.…”

Hydrokinetic tidal energy converter (TEC) technology is yet to become cost competitive with other renewable energy sources. Understanding the interaction between energy production and the costs incurred harvesting that energy may unlock the economic potential of this technology. Although hydrodynamic simulation of TEC arrays has matured over time, including demonstration of how small and large arrays affect the resource, integration of cost modelling is often limited. The advanced ocean energy array techno-economic modelling tool ‘DTOcean’ enables designers to calculate and improve the levelised cost of energy (LCOE) of an array through parametric simulation of the energy extraction, design of the electrical network, moorings and foundations, and simulation of the installation and lifetime operations and maintenance of the array. This work presents a verification of DTOcean’s ability to simulate the techno-economic performance of TEC arrays by reproducing the hypothetical RM1 reference model, a semi-analytical model of a TEC array based in the Tacoma Narrows of Washington state, U.S.A. It is demonstrated that DTOcean can produce a reasonable estimate to the LCOE predicted by the reference model, giving (in Euro cents per kiloWatt hour) 36.69 ¢/kWh against the reference model’s 34.612 ¢/kWh for 10 TECs, while for 50 TECs, DTOcean calculated 20.34 ¢/kWh compared to 17.34 ¢/kWh for the reference model.
