Abstract---- 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.
