    Modelling of a wave energy converter array with non‐linear power take‐off using a mixed time‐domain/frequency‐domain method by Y. Wei, A. Bechlenberg, B. Jayawardhana, A. I. Vakis

    Published 2021-10-01
    “…Abstract A mixed time‐domain/frequency‐domain method is proposed for modelling dense wave energy converter (WEC) arrays with non‐linear power take‐off (PTO). The model is based on a harmonic balance method which describes the system response in the frequency domain, while evaluating the non‐linear PTO force and solving the system equations of motion in the time domain. …”
