| Abstract: |
| Wave energy collected by the power take-off system of a Wave Energy Converter (WEC) is highly fluctuating due to
the wave characteristics. Therefore, an energy storage system is generally needed to absorb the energy fluctuation
to provide a smooth electrical energy generation. This paper focuses on the design optimization of a Hydraulic
Energy Storage and Conversion (HESC) system for WECs. The structure of the HESC system and the mathematical
models of its key components are presented. A case study and design example of a HESC system with appropriate
control strategy is provided. The determination of the ratings of the HESC system is also investigated in order to
achieve optimal system energy efficiency. |
