风电场动态等值建模研究综述

Review of Dynamic Equivalent Modeling for Wind Farm

从风电场动态等值建模(风速等值、集电网络等值、分群聚类、等值参数计算4个步骤)的角度,探讨风电场动态等值建模研究成果。结果表明,风电场动态等值建模有2种方法:一是提高分群精度,获得唯一聚类结果,进行多机等值;二是降低分群精度,转而确定强相关的待辨识参数,辨识出等值机参数。最后,预测了风电场动态等值未来可能的研究方向。

The research achievement in dynamic equivalent modeling of wind farm are analyzed from the aspects of wind farm equivalent modeling four main steps,including wind speed equivalence, collecting network equivalence, clustering and equivalent parameter calculation. There are two kinds of angles, one is to improve the clustering accuracy and obtain the clustering results, conduct multiple machine equivalent; another is to reduce the clustering accuracy, determine relevant parameters to be identified, identify the equivalent parameters. Finally, the future research directions of wind farm are put forward.
