The future of wave energy will depend on developing a new generation of wave energy converters (WECs) that maximize energy extraction and mitigate critical loads while reducing costs. Today's WECs are relatively inefficient compared to their theoretical upper limit and lack the ability to concurrently maximize power recapture and minimize structural loads. Current research in wave energy is trying to overcome inertia in the wave buoys by estimating incoming waves. In most cases a network of buoys are suggested. However, remote detection using radar is preferred because it minimized structural load and increase efficiency.
The technology is a reliable, cost-effective, ocean-wave sensing, feature extraction and data communication system that may be integrated with a wave energy conversion system structure and its controller for feed forward control of wave energy devices. This technology eliminates any need for buoys or other wave sensing apparatus located external to the WECs. The device will provide information about approaching waves to the WEC controller sufficiently in advance that the controller can place WECs into it optimal power conversion state.
