Advanced Controls of Wave Energy Converters May Increase Power Capture Up to 330%

January 21st, 2014|Categories: Computational Modeling & Simulation, Energy, News, News & Events, Partnership, Renewable Energy, Water Power|Tags: , , , , , , , , , , |

Although ocean waves represent an enormous energy resource, most existing WEC designs efficiently produce power only within a narrow wave frequency range. Advanced control of the power-conversion chain can alter this paradigm. Models have shown absorbed-power increases ranging from 100% to 330%. To move from idealized, theoretical paper studies to deployable WEC hard­ware, requires rigorous research. The Department of Energy has recognized this work’s importance in two substantial ways. First, three recent federally funded industry [...]
