Wind farm control is now an established concept, and the industry is beginning to see full-scale demonstration projects and commercialisation of the R&D findings. These so far centre on yaw misalignment and induction control. An important given is that the communication and control technology exists to control wind turbines as a collective; what is lacking in going further with wind farm control is sufficient quantified understanding of the atmospheric physics drivers on wind farm performance. Recent work on Blockage Effects has advanced that understanding, and provided a suite of modelling tools for yield prediction. In particular, the role of temperature gradient in the atmosphere is much better understood. This project will explore the potential for increasing energy yield by controlling a wind farm differently, by responding to the natural variation of the thermal boundary layer. The project will make use of the very latest expertise and tools emerging from the international community's research and development investment in offshore wind. Should the performance improvement anticipated be realised in modelling, it is expected that the offshore wind owner-operator community will eagerly proceed to full scale trial on real wind farms.

风电场控制现已成为一个既定概念，业界开始看到全面的示范项目和研发成果的商业化。到目前为止，这些主要集中在偏航不对中和感应控制上。一个重要的事实是，存在通信和控制技术来控制风力涡轮机作为一个整体；进一步推进风电场控制所缺乏的是对影响风电场性能的大气物理驱动因素的充分量化了解。最近关于阻塞效应的工作推进了这种理解，并提供了一套用于产量预测的建模工具。特别是，人们更好地理解了大气中温度梯度的作用。该项目将通过响应热边界层的自然变化，以不同方式控制风电场，探索提高能源产量的潜力。该项目将利用国际社会在海上风电研发投资中出现的最新专业知识和工具。如果预期的性能改进在建模中得以实现，预计海上风电业主运营商群体将热切地在真实风电场进行全面试验。
