Impedance modelling and grid integration stability evaluation of three‐phase virtual synchronous generator

IET Power Electronics, 2022
Virtual synchronous generator (VSG), which can behave with analogous characteristics as the conventional synchronous generator (SG) and provide voltage and inertia/damping support, is universally regarded as a grid‐friendly interface.

Virtual Synchronization Control Strategy for UHVDC with Secondary Frequency Modulation Based on PI Control

Zhongguo dianli, 2022
Under traditional control strategy, UHVDC transmission system lacks inertia and damping characteristics, so it can't effectively adjust the frequency of AC system dynamically.

Multi-objective optimization of HESS control for optimal frequency regulation in a power system with RE penetration

e-Prime: Advances in Electrical Engineering, Electronics and Energy
Concerns over fossil fuel emissions and their hazardous effects have led to a shift away from conventional power plants and focus more on the expansion of renewable energy sources. This shift has resulted in reduced inertia and resulted in poor frequency

Series Connection of LCC and Full Bridge MMC With DC Fault Ride‐Through Capability for Lightweight HVDC Transmission

Engineering Reports, Volume 8, Issue 4, April 2026.
In this work, we investigate a lightweight HVDC converter topology that combines the strengths of line‐commutated converters (LCC) and full‐bridge modular multilevel converters (MMC) to address the high cost and large footprint of conventional HVDC stations.

Mechanism and Control Analysis of Synchronous Frequency Resonance in Distributed Power Generation System Connected to Grid

Energy Science &Engineering, Volume 14, Issue 4, Page 2263-2276, April 2026.
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.

Stability analysis of parallel virtual synchronous generators and suppression of low‐frequency oscillations

Energy Conversion and Economics, Volume 7, Issue 2, Page 149-161, April 2026.
Abstract With the increasing penetration of power electronic devices in power systems, virtual synchronous generator (VSG) technology has garnered widespread attention for its ability to provide inertia and damping support to the grid. However, while simulating the external characteristics of synchronous generators, this technology also introduces ...

Characteristics and operational control strategies of grid‐forming long‐/short‐duration energy storage systems: A review

Energy Conversion and Economics, Volume 7, Issue 2, Page 127-148, April 2026.
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

Modeling and Control of a Multi‐Energy Microgrid With Wind LVRT and Battery Pre‐Synchronization Strategy

Energy Science &Engineering, Volume 14, Issue 1, Page 266-280, January 2026.
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 ...
