Abstract
Marine hydrokinetic power generation is a relatively new type of renewable generation. Its predecessors, such as wind power generation, hydropower plant generation, geothermal generation, photovoltaic generation, and solar thermal generation, have gained a lot of attention because of their successful implementation. The successful integration of renewable generation into the electric power grid has energized the power system global communities to take the lessons learned, innovations, and market structure to focus on the large potential of marine hydrokinetic to also contribute to the pool of renewable energy generation. This article covers the broad spectrum of marine hydrokinetic generation. The state of the art of power take-off will be discussed. Types of electrical generators will be presented, and the options for implementation will also be presented.
