On Submodularity and Controllability in Complex Dynamical Networks

, 2016
Controllability and observability have long been recognized as fundamental structural properties of dynamical systems, but have recently seen renewed interest in the context of large, complex networks of dynamical systems.

Modelling and control of a back-to-back MMC–HVDC system using ADPSS

The Journal of Engineering, 2019
Back-to-back modular multilevel converter–high-voltage direct current (MMC–HVDC) can realise the asynchronous interconnection of two regional power grids. It can effectively solve the power grid stability problems caused by AC–DC power transfer and avoid

Technology and engineering application of cross area HVDC interconnection system high-precision simulation modeling based on ADPSS

Global Energy Interconnection, 2018
In recent years, a large number of high voltage direct current (HVDC) transmission projects have been connected to AC systems. This has started to have an impact on AC/DC hybrid power grids, particularly receiving terminal power grids.

Series Hybrid Modular Multilevel Converter for HVDC Transmission Systems

IEEE Access
In this paper, a multilevel Voltage Source Converter for HVDC transmission systems is proposed. The topology is based on a string of full-bridge submodules in addition to an unfolder on the converter’s AC-side. Compared to the modular multilevel converter, it has fewer components and has the advantage that almost two third of the switches ...

A fault property identification scheme for the restarting of hybrid HVDC system

International Journal of Electrical Power & Energy Systems
The hybrid HVDC system will be widely used in the future. Since transient faults account for the majority of all overhead line faults, the system restart is essential to restoring the power supply of the hybrid HVDC system.
