Parametric Sensitivity Analysis of a Multi‐Gigawatt Offshore Multi‐Energy System Using Reduced‐Order Models

open access: yesIET Energy Systems Integration, Volume 8, Issue 1, January/December 2026.
ABSTRACT When multiple grid‐forming and grid‐following converters operate within an offshore energy system (OES), dynamic interactions among them can lead to poorly damped oscillations and potential instability. This paper proposes a computationally efficient reduced‐order state‐space modelling framework for small‐signal stability and parametric ...

Power dispatch and voltage control in multiterminal HVDC systems : a flexible approach [PDF]

open access: yes, 2017
This paper deals with the power dispatch and direct voltage control in multiterminal high voltage direct current (MT-HVDC) systems. Generalized voltage droop (GVD) control is adopted for voltage source converters (VSC)s of a MT-HVDC system.

An Overview on VSC-HVDC Power Transmission Systems

open access: yesInternational Journal of Control and Automation, 2016
The Voltage Source Converter based High Voltage Direct Current(VSC-HVDC) is a new generation HVDC technology. Because of the technology of the PWM and the turn- on and turn-off electronic apparatus, VSC-HVDC could make up for the defective of the traditional HVDC. And the development is rapid.

Dual-loop primary frequency regulation controller for VSC-HVDC system [PDF]

open access: yes2017 IEEE Manchester PowerTech, 2017
This paper presents a frequency control mechanism for an AC system through the active and reactive power loops of a VSC-HVDC system. The proposed scheme makes use of the reactive power loop for inertia support by exploiting the voltage-power sensitivity of loads, and active power droop control has been used to provide governor-like support following ...

Multi‐Layer MTDC Protection: Design and Simulation Assessment

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study proposes a novel multi‐layer protection architecture for multi‐terminal DC systems that separates fault current‐limiting and interruption functions. By combining a thyristor‐based fault current limiter with an active resonance circuit breaker, the scheme significantly reduces peak fault currents and di/dt stress, enabling a more compact ...

Impact of DC Breaker Systems on Multiterminal VSC-HVDC Stability [PDF]

open access: yesIEEE 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

Stability and Synchronization of MMC‐HVDC Systems Using SRF and Inertia‐Based PLLs

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study investigates the influence of synchronous reference frame PLL (SRF‐PLL) and the inertia PLL (IPLL) on the stability of grid‐connected modular multilevel converter high voltage direct current (MMC‐HVDC) systems. The findings highlight intrinsic stability limitations of PLL‐based systems, offering insights toward more stable, PLL‐less ...
