A Novel Coordinated Control Strategy for VSG to Enhance Power Tracking Speed Without Degrading Inertia Support Capability

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
ABSTRACT The virtual synchronous generator (VSG), as a representative grid‐forming control method, has become a key technology in distributed renewable energy systems. However, there exists an inherent trade‐off between fast power reference tracking and high virtual inertia support in conventional VSG control.

Fault current characterisation in VSC-based HVDC systems [PDF]

, 2016
The DC-side line faults in high-voltage direct-current (HVDC) systems utilising voltage-source converters (VSCs) are a major concern for multi-terminal HVDC systems in which complete isolation of the faulted system is not a viable option.

Transient stability analysis in multi-terminal VSC-HVDC grids [PDF]

2016 Power Systems Computation Conference (PSCC), 2016
A novel approach to transient stability analysis in multi-terminal high voltage direct current (MTDC) grids is presented in this paper. A symmetrical three-phase fault in an ac grid connected to a rectifier terminal of the MTDC grid causes the power injected into the dc grid to decrease, which in turn leads to a lower dc voltage in the MTDC grid. If dc

An Optimised Independent Arm Modulation Strategy Driven by Energy Balance Mechanism for Circulating Current Suppression in Arm‐Multiplexing Modular Multilevel Converters

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
The arm‐multiplexing modular multilevel converter (AM‐MMC) is a lightweight, high‐power‐density topology whose conventional modulation strategies require large circulating currents to maintain energy balance. This paper establishes a time‐domain analytical model of the AM‐MMC energy‐balance mechanism and proposes an optimised independent arm modulation

Coordinated Planning of Flexibility Resources for HVDC‐Connected Renewable Base and Load Center: A CVaR‐Based Probabilistic Approach

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
This paper proposes a conditional value‐at‐risk (CVaR)‐based coordinated planning framework to address the volatility and uncertainty in high voltage direct current (HVDC)‐interconnected systems. By jointly optimizing storage deployment, thermal retrofits, and reserve allocation, the method effectively quantifies and mitigates tail risks.
