Sea energy conversion

The present workexposes the modelling of an electric energy generation system through the waves and the marine currents.

The present work exposes the modelling of an electric energy generation system through the waves and the marine currents. The model includes both the wave and current dynamics part, as well as the dynamics of the mechanical system, the electromechanical system and, finally, the power electronics part. The proposal is constituted by the models of (i) a buoy and turbine for marine currents; (ii) a gearbox; (iii) a permanent magnet synchronous generator; (iv) an AC/DC rectifier bridge; (v) a DC/DC converter; (vi) a battery; (vii) a DC/AC inverter and, finally, (viii) an electric load.
