Generalized Voltage-based State-Space Modelling of Modular Multilevel Converters with Constant Equilibrium in Steady-State [PDF]
, 2017 This paper demonstrates that the sum and difference of the upper and lower arm voltages are suitable variables for deriving a generalized state-space model of an MMC which settles at a constant equilibrium in steady-state operation, while including the ...

Impact of DC Breaker Systems on Multiterminal VSC-HVDC Stability [PDF]
IEEE Transactions on Power Delivery, 2016 The use of VSC-HVDC grids for offshore wind farm integration will require the use of dc breaker systems and they, at present, will require dc reactors to limit the rate of rise of fault current. The introduction of large dc reactors throughout a VSCHVDC system can have significant impact on its stable operation and will require additional control. This

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.

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

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.
