Optimization and Time-Domain Simulation of the SEAREV Wave Energy Converter

Abstract

This paper introduces a new second generation wave energy converter concept named SEAREV [Systeme Electrique Autonome de Recuperation d’Energie des Vagues]. The working principle and linearized equations of the device are described. It is shown how energy absorption depends on the shape of the external floating body and on the mechanical characteristics of the moving mass. This allows to numerically optimize the geometry of the device. Latching control is used to further improve the capture width of the system, with success in regular waves.
