Abstract
In this work an Oscillating Wave Surge Converter (OWSC) for harvesting energy from wave motion in a channel is considered. A conversion from wave energy to electric energy is achieved through an oscillating flab gate hinged on the seabed and equipped with a directly-driven power take-off system, employing a high efficiency speed multiplier which drives a low speed alternator. Processing of the generated voltage is described by referring to a simple exemplary resistive harvesting circuit. In order to optimize the extracted energy, a semi-active control strategy based on a Bang-Bang technique is introduced. As a result, numerical solution of the corresponding dynamical problem proves the effectiveness of the adopted control strategy, highlighting an enhance up to 21% in the average harvested power when compared to the case without control.
