Abstract :
This paper proposes control strategies for arrays of direct drive wave energy converters. Two control strategies taken from the theoretical study of the hydrodynamic properties of oscillating bodies are applied to a wave energy converter (WEC) system including a linear generator (LG) and voltage source converter system. The purpose of this study is to investigate the feasibility of the control strategies on WECs working in arrays. Simulations of an array of direct-drive WECs connected together by DC link were developed in Matlab/Simulink. The study concludes with a discussion on their feasibility in terms of electrical power generated and the deployment suitability in real seas.
