波浪能转换器（WEC）的优化是在能源市场上获得有竞争力的设备的一个非常重要的课题。波浪能是一种可再生资源，可以为未来的可持续发展做出重大贡献。研究正在进行中，以降低成本和增加捕获的能量。这项工作的目的是优化的WaveSub装置由多个浮子在一条线上通过调查的影响，6个不同的设计参数，如浮子的数量。在这里，我们表明，与LCOE降低约21%的单浮子配置相比，6个浮子的多浮子配置在平准化能源成本（LCOE）方面更具竞争力。我们证明，该装置的多浮配置降低了LCOE，特别是因为减少了电网连接，安装，控制和系泊成本。从功率捕获的角度来看，优化的多浮子配置仍然具有与单浮子配置相似的容量因子。这项研究从优化的角度为WECs的进一步发展提供了重要的指示。这些令人鼓舞的结果表明，更复杂的，优化的，多浮子配置可以在未来进行研究。
Optimisation of Wave Energy Converters (WECs) is a very important topic to obtain competitive devices in the energy market. Wave energy is a renewable resource that could contribute significantly to a future sustainable world. Research is on-going to reduce costs and increase the amount of energy captured. This work aims to optimise a WaveSub device made up of multiple floats in a line by investigating the influence of 6 different design parameters such as the number of floats. Here we show that a multi-float configuration of 6 floats is more competitive in terms of Levelised Cost Of Energy (LCOE) compared to a single float configuration with a LCOE reduction of around 21%. We demonstrate that multi-float configurations of this device reduce the LCOE especially because of the reduction of grid connection, installation, control and mooring costs. From the power capture perspective, optimized multi-float configurations still have similar capacity factors to the single float configuration. This research gives important indications for further development of the WECs from an optimisation perspective. These promising results show that more complex, optimized, multi-float configurations could be investigated in future.
