Grid power integration technologies for offshore ocean wave energy

In this paper, the advanced electric technologies for grid power integration of different offshore wave energy conversion devices are presented. The electrical connection configurations for integrating the electric power of the multi wave energy conversion devices such as the Oscillating Water Column, Pelamis, the Wave Point Absorbers and the Wave Dragon are developed by employing the most efficient low cost grid interface electrical technologies based on the advanced power electronics. The bi-directional power converter is employed for wide-range variable speed operation of wave energy conversion device to reduce the power output fluctuations and improve the whole power generation efficiency.
