To carry out a feasibility study of the enhancement in average output of wave energy converting devices that is possible with the incorporation of Deterministic Sea Wave Prediction (without increased risk of wave damage to the converters). The work will explore operation of and benefits from being able to operate wave energy converters in the so called quiescent periods that occur between large waves that could damage the converter. During the large wave intervals the converter will be decoupled from the wave system so lowering the structural loading to a safe level. Foreward wave prediction of a few seconds is required due to the finite time required for shutdown. Furthermore work will be undertaken on the effects on energy output of using wave prediction to control adaptive dynamical elements within converters so as to optimise the performance in real time to each incomming wave group. There will be three phases: (i) a study of the gains stemming from the ability to operate in quiescent intervals, independent of how theses are identified, (ii) a study of deterministic wave prediction explicitly for wave farm applications and their performance and (iii) an integration of the first two studies to allow assessments of the gains acheivable incorporting the perfromance capabilites of actual wave prediction systems. In addition to the paper and simulation work typically affordable in faesibility studies the key novel scientific elements (mainly the prediction aspects) will but the subject of actual field studies. This is possible by virtue of the proposed project falling under the umbrella of the new Penninsular Research Institute for Marine and Renewable Energy (PRIMARE) which is linked to the commercial South West Wave Hub. The project will have access to the PRIMARE wave and current sensor grid which is an intensively instrumented 3km by 4km area of sea 20km off North Cornwal corresponding to the site for a group of commercial wave energy converters.

进行一项可行性研究，探讨加入确定性海浪预报后可提高波能转换装置的平均产量的可行性(而不会增加对转换器造成海浪损坏的风险)。这项工作将探索波能转换器在所谓的静止期运行的好处，这种静止期发生在可能损坏转换器的大浪之间。在大波间隔期间，转换器将与波浪系统解耦，从而将结构载荷降低到安全水平。由于停机所需的时间有限，因此需要几秒钟的前向波预报。此外，还将研究使用波预测来控制变流器内的自适应动态元件对能量输出的影响，以实时优化每个进入波组的性能。将分为三个阶段：(I)研究由在静止区间运行的能力产生的收益，而不考虑如何识别这些收益；(Ii)明确针对波场应用及其性能的确定性波浪预报的研究；以及(Iii)前两个研究的整合，以便能够评估结合实际波浪预报系统的性能的可获得的收益。除了通常在可行性研究中负担得起的论文和模拟工作之外，关键的新颖科学要素(主要是预测方面)将成为实际实地研究的主题。这是可能的，因为拟议的项目属于新的彭尼岛海洋和可再生能源研究所(Primare)的保护伞，该研究所与商业西南波枢纽相连。该项目将使用Primare波浪和电流传感器电网，这是一个密集的仪器，位于北康沃尔20公里外3公里乘4公里的海域，与一组商业波能转换器的选址相对应。
