Small‐signal modeling reveals that insufficient system damping positions conjugate poles near the imaginary axis, fundamentally explaining the SFR mechanism. A virtual resistance control is consequently proposed to damp the resonance and effectively suppress SFR, which is validated through Hardware‐in‐the‐Loop experiments.

Abstract Energy storage systems (ESSs) are increasingly critical for maintaining the stability and flexibility in power systems with rising renewable penetration. Grid‐forming (GFM) ESSs have emerged as a pivotal technology, capable of providing essential voltage and frequency support by establishing grid references in converter‐dominated systems. This

This study establishes a hybrid microgrid model integrating a Doubly Fed Induction Generator (DFIG), a photovoltaic (PV) array, and a battery energy storage system, and proposes a coordinated control framework. The DFIG regulates DC‐bus voltage through the grid‐side converter and performs maximum power tracking via the rotor‐side converter, while the ...

Low‐Frequency Oscillation Suppression Strategy Based on NPOD‐SVC‐VSG Grid‐Connected System
ABSTRACT The power control loop in a virtual synchronous generator (VSG) exhibits inherently insufficient damping, making it prone to low‐frequency oscillation (LFO) under disturbances. Moreover, the dynamic coupling between active and reactive power can induce unnecessary reactive power fluctuations during active power transfer.
