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，它已经是可用的最便宜的发电形式。海上风能目前在适合浅海的地区发挥着重要且迅速增长的作用。海上风力涡轮机刚刚开始商业化安装，进一步向漂浮的海上风力涡轮机迈出一步，可以通过允许使用更深的海域来极大地增加潜在的海上风力资源。多年来的研究已经导致了今天风力发电场中看到的非常大、高效和具有成本效益的风力涡轮机设计。最近的许多研究都集中在更高效、更具成本效益的风电场安装和运营上。人们对新的风电场控制策略非常感兴趣，这种策略可以改善风电场的整体运行，而不是仅仅控制每个风力涡轮机，就好像它与邻近的风力涡轮机独立运行一样。例如，一种称为尾流转向的策略，试图将每个涡轮机的尾流偏离下游的涡轮机，从而通过减少疲劳损伤来增加总体发电量和更长的寿命。这项研究将专注于在漂浮的海上风电场环境中使用尾流转向。需要更多的研究来更深入地了解尾流效应，特别是在海上环境典型的风条件下，以便设计出最有效的控制策略。DNV GL、达勒姆大学和海洋流动能源公司已合作应用于这一研发计划，以研究这一创新控制技术在浮式海上风电场应用的可行性。这项研究建议的主要目标包括：*增加使用尾流操控的信心；*找出在浮式海上风电场使用尾流操控的技术挑战和优势；*以StarFloat浮式平台设计为基准，分析使用尾流操控的影响；*分析应用尾流操控对海上漂浮风电场经济表现的影响。这项研究将与NREL牵头的美国财团合作进行，该财团已成立，以研究固定海上风电场的类似控制策略。专业知识和风电场数据的共享将导致尾流建模技术的改进，这将有助于将尾流转向的技术和经济利益带到不断增长的美国和英国海上风电场市场。

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.
