The objective of this thesis is to investigate and mitigate power fluctuations of tethered undersea kite (TUSK) system by modelling a TUSK plant power output for a given trajectory and suggest a co-ordination strategy for several plants in a farm. This involves synchronising the operations of two or more plants by time shifting a second plant to compliment the first plant. The shifting of a plant relative to another momentarily disturb power production. Multiple plants can be coupled to optimize the shifting required while minimising power disruption. Therefore, the collection of plants, known as a tidal farm, will produce a more regular power output during production on par with traditional marine turbines.
