| This paper presents a model predictive current control (MPCC) for three-phase four-switch converter (TPFSC) connected to surface permanent magnet synchronous generators (SPMSG) in oscillating water column (OWC) wave energy plants. The proposed MPCC for TPFSC follows fast and accurately the current references in the synchronous reference frame whereas the switching frequency of the IGBTs is fixed and low. This method minimizes the errors in the currents and its fast response time makes it suitable for the power take-off (PTO) systems present in wave energy converters (WECs). Furthermore, the system features a fast capacitor voltage offset suppression control. The dynamic performance and the voltage offset control of the proposed strategy for TPFSC feeding SPMSG is evaluated in Simulink environment. Later, the experimental studies are carried out on an 8.7 kW laboratory SPMSG prototype. Finally, the capability of the proposed method to harvest the maximum energy from irregular waves is assessed using an OWC power plant emulator. | |
