Title: Marine Tidal and Wave Energy Converters: Technologies, Conversions, Grid Interface, and Control

Abstract / Outline
The world wide potential of electric power generation from marine tidal currents and waves is enormous. High load factors resulting from the fluid properties and the predictable resource characteristics make these energy resources attractive and advantageous for power generation and advantageous when compared to other renewable energies with unpredictability in availability. The technologies are just beginning to reach viability to make them potential commercial power sources. While just a few small projects currently exist, the technology is advancing rapidly and has huge potential for generating bulk power. Moreover, international treaties related to climate control and dwindling fossil fuel resources have encouraged harnessing energy sustainably from such renewable sources. Several demonstrative projects have been scheduled to capture tidal and wave energies. A number of these projects have now reached a relatively mature stage and are close to completion. However, very little is known to the academic world about these technologies beyond basics energy conversion principle. While research emphasis is more towards hydrodynamics and turbine design, very limited activities are witnessed in power conversion interface, control and power quality aspects, which are of vital importance for their successful integration to the grid or to standalone micro‐grid. Regarding this emerging and promising area of research, this tutorial aims to highlight and address the following key topics and issues: 1) First the marine renewable energies context will presented and the huge potential for generating bulk power highlighted; 2) Then the main and viable tidal and wave energy converters technologies will be presented; 3) Finally, the key issue of grid connection will be addressed and some solution presented based on different storage technologies.
