Calvário, M., Gaspar, J.F., Kamarlouei, M. e Guedes Soares, C. (2019), “Optimal power take-off parameters for a bottom-hinged plate wave energy converter”, Proceedings of the 13th European Wave and Tidal Energy Conference (EWTEC 2019), 1-6 September, Napoli, Italy
The objective of this paper is to derive the optimal parameters of an oil-hydraulic power take-off system for a bottom-hinged plate wave energy converter and to verify the impact of the state-of-the-art reactive control strategy on the converter performance. The power take-off concept relies on a concept of two-single rod oil-hydraulic cylinders working with a reciprocating movement on both sides of the bottom plate. The concept takes advantage of two possible hydraulic configurations to maximize their efficiency. The system is modelled with different controller’s, whose parameters are optimized with genetic algorithms in order to maximize the harvested power. The mechanical interface between the power take-off and converter is also optimized considering technological constraints on the power take-off system and converter motions. The simulations are performed for different sea sate conditions.
