Power Optimization of Wave Energy Converter (WEC) Arrray Based on Sea Conditions of a Wind Farm

  Introduction  In order to respond to the national initiative of intensive sea use, develop clean energy, and contribute to carbon neutralization, a preliminary analysis was conducted on the multi-energy integration mode of offshore wind power and wave energy devices, and the WEC was optimized to achieve higher power output.

  Method  Based on potential flow theory, the floating fan platform - WEC array was simulated to analyze the influence of the dimension and the inherent period of the WEC on the output power of the WEC.

  Result  The simulation results show that under the same inherent period, the flatter the WEC is, the greater the total power of the WEC array is, and the economic difference of the WEC is small. For sea conditions, the economic difference of WEC array under different inherent periods is great, so it should be considered comprehensively.

  Conclusion  In the known sea conditions, the inherent period and the dimenson of WECs can be optimized to achieve higher power output and increase energy output per unit sea area.
