Method of DFIG Cooperating with SVG to Suppress Low-Frequency Oscillation in Power Systems

Zhongguo dianli, 2020
With the increasing penetration of wind power, when the power system is insufficiently damped, low-frequency oscillations are likely to occur. Doubly fed induction generation (DFIG) can decouple the control of active and reactive power, which helps ...

Towards practical oscillation detection in wind farms: Comparative study of AI models, novel metrics, and edge implementations

Energy Conversion and Economics, EarlyView.
Abstract Fast oscillations observed in wind farms and other renewable energy systems interfaced with power grids must be addressed promptly to prevent devastating shutdown and damage. Existing approaches mainly target high‐magnitude oscillations using data‐intensive convolutional neural networks (CNNs), leading to delayed detection and overlooking mild

Impedance characteristics of DFIGs considering the impacts of DFIG numbers and its application on SSR analysis

IOP Conference Series: Materials Science and Engineering, 2017
Sub-synchronous resonance (SSR) occurred in the power system with both Doubly Fed Induction Generators (DFIGs) and series-compensated lines. There have been several papers focusing on the analysis of such SSR phenomenon. To the authors' knowledge, the impacts of DFIG numbers are seldom considered in existing papers.
