Overview of Broadband Oscillation Mitigation of New Energy Generation Power System Based on Impedance Perspective
With the increasing adoption of renewable power electronic devices in power systems,the"source-grid-load"structure is evolving towards a power electronics-based paradigm.This transformation has led to complex dynamic interactions and prominent broadband stability issues.In recent years,impedance analysis methods have gained significant attention in addressing these new stability challenges.Various impedance control methods have emerged as crucial tools for solving wide-frequency oscillation problems.To further investigate this issue,the present study reviews typical oscillation cases both domestically and internationally.Then,based on an impedance perspective,the existing oscillation suppression methods and engineering solutions are classified and summarized into three levels:equipment,field station,and system.Finally,the challenges and problems associated with existing oscillation suppression techniques in power electronic power systems are summarized and the future research directions for developing impedance-based suppression methods are prospected.
