Elucidation of the hydrodynamics in newly-arised innovative floating systems toward highly-efficient ocean renewable energy conversion

海浪能可以通过一组部署在一起的波能转换器来利用，从海浪的动能发电。这样的波能阵列往往位于海岸附近或近海，由浮标等多个装置组成，通过输电与电网相连。本文利用多次散射理论对阵列在多向不规则波中的性能进行了评估。基于每个海况的气象发生概率和每个换流站的功率矩阵，定量地评估了当地站点的年发电量。此外，还利用所提出的数值方法，在考虑一年内海况变化的情况下，为给定的阵列选择了最合适的位置。

Ocean wave energy can be harnessed by a group of wave energy converters deployed together to generate electricity from the kinetic energy of ocean waves. Such wave energy arrays are often located near the coast or offshore, consisting of multiple devices, such as floating buoys, and connected to the grid through power transmission. In the present work, the multiple scattering theory is employed to assess the array performance in multi-directional irregular waves. Based on the meteorological occurrence probability of each sea state and the power matrix of each converter, the annual power production at a localised site is evaluated quantitively. Moreover, the developed numerical method is used to select the most appropriate site for given arrays considering the varying sea states in a year.
