Abstract

The fast frequency support (FFS) towards frequency trajectory optimization provides a system view for the frequency regulation of wind farms (WFs). However, the existing frequency trajectory optimization-based FFS generally relies on the accurate governor dynamics model of synchronous generators (SGs), which aggrandizes the difficulty of controller implementation. In this paper, a proportional-integral (PI) based FFS of WFs is designed for tracking the optimal frequency trajectory, which gets rid of the dependence on the governor model. Firstly, the prototypical PI-based FFS of WFs is proposed and its feasibility for tracking the optimal frequency trajectory is analyzed and demonstrated. Then, based on the “frequency-RoCoF” form of the optimal frequency trajectory, a more practical PI controller is constructed, avoiding the time dependence of the prototypical PI controller. Besides, an adaptive gain associated with PI parameters is designed for multi-WF coordination. Finally, the validity of the proposed method is verified in both the single-WF system and the multi-WF system.

风电场的无模型快速频率支持以跟踪最佳频率轨迹

面向频率轨迹优化的快速频率支持（FFS）为风电场（WFs）的频率调节提供了系统视图。然而，现有的基于频率轨迹优化的 FFS 通常依赖于同步发电机 (SG) 的精确调速器动力学模型，这增加了控制器实现的难度。本文设计了一种基于比例积分（PI）的风力发电机 FFS，用于跟踪最优频率轨迹，摆脱了对调速器模型的依赖。首先，提出了基于 PI 的 WFs FFS 原型，并分析和论证了其跟踪最佳频率轨迹的可行性。然后，根据最佳频率轨迹的 "频率-RoCoF "形式，构建了一个更实用的 PI 控制器，避免了原型 PI 控制器的时间依赖性。此外，还为多 WF 协调设计了与 PI 参数相关的自适应增益。最后，在单 WF 系统和多 WF 系统中验证了所提方法的有效性。
