Use of Wind Farm Control on floating platforms for the U.S. offshore wind market, CONFLOWS

风能预计将在未来几十年成为全球能源供应的主要贡献者，在许多地区，它已经是最便宜的发电方式。目前，海上风能在适宜的浅海地区发挥着重要且迅速增长的作用。漂浮式海上风力涡轮机的进一步发展，正开始商业化安装，可以通过允许使用更深的海域，大规模增加潜在的海上风力资源。经过多年的研究，今天的风电场设计出了非常大、高效、经济的风力涡轮机。最近的许多研究都集中在更有效和更具成本效益的风力发电厂的安装和运行上。人们对新的风电场控制策略非常感兴趣，这种策略可以改善整个风电场的运行，而不仅仅是控制每个风力涡轮机，就好像它与邻居隔绝一样。例如，一种被称为“尾流转向”的策略，试图使每个涡轮机的尾流远离下游涡轮机，从而增加总发电量，并通过减少疲劳损伤而延长使用寿命。本研究将重点关注在浮动海上风电场环境下尾流转向的使用。为了更深入地了解尾流效应，特别是在海上典型的风力条件下，需要进行更多的研究，以便设计出最有效的控制策略。dnv GL、杜伦大学和ocean Flow energy合作申请了这一研发项目，以研究这种创新控制技术在海上浮式风力发电场上的可行性。这项研究计划的主要目标包括：*增加对使用尾流转向的信心，*确定在浮动海上风电场上使用尾流转向的技术挑战和优势，*以Starfloat浮动平台设计为基准分析使用尾流转向的效果，*分析应用尾流转向对浮动海上风电场经济性能的影响。这项研究将与一个由NREL领导的美国财团合作进行，该财团的成立是为了研究固定海上风电场的类似控制策略。专业知识和风力发电场数据的共享将导致尾流建模技术的改进，这将有助于为不断增长的美国和英国海上风力发电场市场带来尾流转向的技术和经济效益。

Wind energy is expected to be a major contributor to the global energy supply in the coming decades, and in many areas it is already the cheapest form of electricity generation available. Offshore wind energy is now playing a significant and rapidly increasing role in areas with suitable shallow seas. A further step to floating offshore wind turbines, which are just beginning to be installed commercially, could massively increase the potential offshore wind resource by allowing deeper sea areas to be used.Research over many years has led to the very large, efficient and cost-effective wind turbine designs seen in today's wind farms. Much recent research has focussed on more efficient and cost-effective installation and operation of wind farms. There is serious interest in novel wind farm control strategies which can improve the operation of the wind farm as a whole, rather than just controlling each wind turbine as if it was operating in isolation from its neighbours. One strategy for example, known as 'wake steering', attempts to deflect each turbine's wake away from downstream turbines, allowing increased overall power production, and longer lifetime through reduced fatigue damage.This study will focus on the use of wake steering in a floating offshore wind farm context. More research is required to get a deeper understanding of the wake effects, particularly in wind conditions typical of offshore environments, so that the most effective control strategies can be devised._DNV GL, Durham University_ and _Ocean Flow Energy_ have partnered to apply to this R&D programme in order to investigate the feasibility of this innovative control technology on floating-offshore wind farms. The main objectives of this research proposal include:* increasing confidence in the use of wake steering,* identifying technical challenges and advantages of using wake steering on floating offshore wind farms,* analysing the effects of the use of wake steering using the Starfloat floating platform design as a benchmark,* analysing the effects of the application of wake steering on the economic performance of a floating offshore wind farm.This research will be carried out in cooperation with a US consortium, led by NREL, which has been formed to investigate similar control strategies for fixed offshore wind farms. Sharing of expertise and wind farm data will lead to improved wake modelling techniques which will help bring the technical and economic benefits of wake steering to the growing US and UK offshore wind farm markets.
