The design of combined energy generation using airborne and ocean current kites in offshore

In this paper, unlike existing generation methods of using wind and ocean current energy, a combined power generation method is used. This device uses a kite to generate higher amount of energy generation compare to turbine type generation assuming that the rotor disc area and kite area are same. The method of using the kite has advantages in terms of cost and the quantity of energy that could be secured. The windy coastal areas have a fast ocean current velocity. So it is possible to increase total energy generation by combining wind and ocean current power on one platform. The ultimate conclusions are as follows: (1) Enlarging the kite area increases the available energy and reduce the costs of installation and unit generation. (2) Compared with existing wind and ocean current power generators that use turbine, maintenance is easier than original. (3) In complex power generation as mentioned, the parts of obtaining energy are different with general wind power generation and ocean power generation. This parts are not fixed but moving in the side of wind direction and the side of ocean current flow direction. So more large energy can be obtained even at low wind and ocean current flow. Particularly, the ESS method of using the head of water drop is easy to apply to this complex power generation platform.
