Electro-Mechanical WEC Stabilization for Onshore Wave Energy Exploitation

The energy generated from harnessing sea waves is considered as a potential solution to the energy needs of small islands. The fundamental problem with the energy produced by wave energy devices is the quality of the energy itself, as it is deeply influenced by the unpredictable conditions inherent to the wave motion. Indeed, the energy produced from a direct connection between the collector and the generator is profoundly variable in terms of voltage and frequency. This prevents its direct input into the grid, as the latter is characterized by fixed frequency and voltage. The objective of this paper is to demonstrate how it is possible to normalize such energy by an electro-mechanical stabilizer.
