Abstract

As wave energy converters (WECs) progress toward largescale commercialization, deployment in arrays is required to achieve higher power capacities, where hydrodynamic interactions strongly influence performance. While Power Take-Off (PTO) systems play a key role in both WEC dynamics and cost, PTO sizing has mainly been studied for standalone devices. This work investigates the combined effects of PTO sizing and array configuration on the techno-economic performance of WEC arrays. A reference array of five heaving point absorbers is analyzed using numerical hydrodynamic modeling with Nemoh and a spectral-domain approach incorporating PTO force capping via statistical linearization, alongside a preliminary cost model. Three representative array configurations are examined, and the results show that PTO sizing is strongly configuration-dependent and can significantly improve overall techno-economic performance, assessed through the levelized cost of energy.
