A multi-point-absorber wave-energy converter for the stabilization of output power

A point-absorber wave-energy converter is commonly used because its structure is simple and efficient. This paper proposes a multi-point absorber wave-energy converter (MPAWEC) in which hydrostatic transmission is used to convert wave energy into electric energy. With multi-point absorbers and a high-pressure accumulator, the design offers advantages such as greater energy harvesting and stabilization of the output power. A small-scale test rig was fabricated for experiments. All of the components of the MPAWEC were mathematically modeled, and simulation results were compared with the experimental results. The overall efficiency of the proposed system is 27.3%.
