这项研究提出了一种通用方法，用于更准确地评估具有高渗透率的风力发电网络的性能。该方法允许分析所有实施规模的风力发电，包括以低压连接的高度分散的微型和小型单个风力涡轮机，以及以中压连接到配电网的中小型风电场（WF）。现有文献中仍然缺少这种用于建模风力发电的“全尺度”方法。应用先进的风能资源中尺度大气模型来生成所有实施尺度下的真实输入风速数据，并使用简单但准确的总风力发电模型来计算发电功率输出。所提出的方法是专门用于评估嵌入式风力发电对输电系统规划和运行的影响。该方法进行了验证，使用一个实际的英国输电网络，从几个WF和系统批量负载供应点的测量的情况下，研究证明其适用性和评估其局限性。
This study presents a general methodology for a more accurate assessment of performance of networks with a high penetration of wind‐based energy generation. The methodology allows to analyse wind generation at all scales of implementation, including highly dispersed micro‐ and small‐scale individual wind turbines connected at low voltage, as well as small‐ to medium‐size wind farms (WFs) connected to distribution networks at medium voltage. Such an ‘all‐scale’ approach for modelling wind generation is still missing from existing literature. An advanced mesoscale atmospheric model of wind energy resources is applied to generate realistic input wind speed data at all scales of implementation, from which generated power outputs are calculated using simple but accurate aggregate wind generation models. The presented methodology is specifically intended for assessing the impact of embedded wind generation on transmission system planning and operation. The methodology is validated using a case study of an actual section of the UK transmission network, where measurements from several WFs and system bulk load supply points are used to demonstrate its applicability and assess its limitations.
