Modelling and control stability analysis of grid‐connected bifacial PV power generation systems using virtual synchronous generator technology

open access: yesIET Energy Systems Integration, Volume 7, Issue 1, January/December 2025.
Abstract In recent years, bifacial solar panels are accelerating to replace single‐side PV devices in traditional PV power generation system due to their high utilisation rate and price advantages. This makes the stability and control strategy of grid‐connected bifacial PV systems (GCBPVS) to be different from the traditional method after it is ...

Grid‐Forming Converters Integrated Power System Frequency Response Model: A Parameter Estimation Approach

open access: yesIET Energy Systems Integration, Volume 7, Issue 1, January/December 2025.
ABSTRACT This paper deals with an updated frequency response model (FRM) for modern power grids incorporating a grid‐forming (GFM) converter. This model aims to accurately capture the dynamic frequency behaviour of the GFM converters integrated into large‐scale power systems.

Virtual Inertia Planning for Enhancing Grid Stability in Low‐Inertia Systems

open access: yesIET Energy Systems Integration, Volume 7, Issue 1, January/December 2025.
ABSTRACT The global power grid is undergoing a significant transition with the increasing integration of renewable energy sources (RESs). This shift, characterised by a decline in conventional synchronous generators and a rise in inverter‐based RESs, has resulted in reduced grid inertia, posing substantial challenges to frequency stability.

Transient Stability Improvement of Power System by Assigning Dynamic Converter Limits to Superconducting Magnetic Energy Storage

open access: yesIET Energy Systems Integration, Volume 7, Issue 1, January/December 2025.
ABSTRACT The virtual synchronous generator (VSG) concept is implemented to mimic the properties of synchronous generators and therefore improve the stability of modern power systems. Superconducting magnetic energy storage (SMES) is able to rapidly absorb power in the case of a fault and becomes completely charged due to capacity constraints.

Analysis of broadband oscillation mechanisms in grid‐forming and grid‐following converters based on virtual synchronous generator

open access: yesIET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
Positive and negative sequence impedance models considering small disturbances in phase angle and voltage are established using harmonic linearization, and the model's accuracy is validated using sweep frequency methods. Analyse the dominant control links in different frequency bands of VSG_GFM and VSG_GFL broadband impedance characteristics. Using the
