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.

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.

Optimization of Wind Power Curtailment by OPF in Hybrid AC/VSC-HVDC Systems With DC Voltage Constraints

IEEE Access, 2023
This paper proposes an optimization method for wind power output curtailment based on optimal power flow (OPF) analysis. The wind curtailment ratio is incorporated as a controllable variable in the OPF formulation.

Accurate Harmonic Voltage Measurement Based on Series Resistive‐Capacitive Divider for Gas‐Insulated Switchgear

IET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.
A series resistive‐capacitive divider for harmonic voltage measurement of gas‐insulated switchgear was studied. It can step down the voltage while amplifying the proportion of harmonics in the total sensed voltage, thereby increasing the significant figure for the measurement and enabling the accurate measurement of high‐order, low‐amplitude harmonics.

Inter-harmonics in multi-terminal VSC-based HVDC systems

Journal of Modern Power Systems and Clean Energy, 2016
Multi-terminal voltage sourced converter (VSC)-based high voltage direct current (HVDC) system composes of a number of VSCs connected to an HVDC grid (or dc grid). The dc grid is often configured by cable interconnections between converter stations, thus
