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

海洋波浪能可以通过一组波浪能转换器来利用，这些波浪能转换器被部署在一起，以从海洋波浪的动能中产生电力。这种波浪能阵列通常位于海岸附近或近海，由多个装置组成，例如浮动浮标，并通过电力传输连接到电网。本文采用多次散射理论来评估阵列在多向不规则波中的性能。根据各海况的气象发生概率和各换流器的功率矩阵，定量地评估了局部站点的年发电量。此外，开发的数值方法是用来选择最合适的网站，考虑到在一年中不断变化的海况给定阵列。

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.
