| Abstract |
Many grid connection concerns, such as maximum power absorption and improved power quality, are increasingly gaining research interest in the wave energy sector, as several wave energy converter (WEC) concepts approach their near-commercial deployments. In this regard, several wave energy control solutions have been proposed without a clear sign of a straightforward preferred candidate. Therefore, this paper aims at contributing to the wave energy field by proposing a novel WEC control concept, based on an adaptive vectorial approach for achieving maximum power absorption of the wave energy resource. Thanks to the adaptive characteristic of the proposed controller, maximum energy extraction can be achieved at any time regardless of the dominant frequency characteristics of the waves. Finally, the proposed vectorial approach further contributes in reducing the large instantaneous power fluctuations when operating at maximum power extraction conditions. |
