Distributed Voltage and Current Control of Multi-Terminal High-Voltage Direct Current Transmission Systems [PDF]
IFAC Proceedings Volumes, 2014 High-voltage direct current (HVDC) is a commonly used technology for long-distance power transmission, due to its low resistive losses and low costs. In this paper, a novel distributed controller for multi-terminal HVDC (MTDC) systems is proposed. Under certain conditions on the controller gains, it is shown to stabilize the MTDC system. The controller

Hybrid Models of Alternative Current Filter for Hvdc
MATEC Web of Conferences, 2017 Based on a hybrid simulation concept of HVDC, the developed hybrid AC filter models, providing the sufficiently full and adequate modeling of all single continuous spectrum of quasi-steady-state and transient processes in the filter, are presented.

HVDC (High Voltage Direct Current) Transmission System: A Review Paper [PDF]
Gyancity Journal of Engineering and Technology, 2018 Back in the early days of electricity supply, AC (alternating current) was adopted for power transmission because it could be stepped up or down as needed by transformers and because it could be interrupted more easily than DC (direct current). High-voltage AC grids evolved as an efficient way to connect existing islands of distribution grids and large

Inertia emulation control strategy for VSC-HVDC transmission systems [PDF]
, 2013 There is concern that the levels of inertia in power systems may decrease in the future, due to increased levels of energy being provided from renewable sources, which typically have little or no inertia.
