Hybrid HVDC system for power transmission to island networks

2003 IEEE PES Transmission and Distribution Conference and Exposition (IEEE Cat. No.03CH37495), 2004
A hybrid system, comprising a line commutated thyristor HVDC converter and a STATCOM, is proposed in this paper for the connection of networks with no synchronous generation to a main grid. The proposed system combines the robust performance and low capital cost and power loss of a line-commutated HVDC converter, with the fast dynamic performance of a ...

Development of a parameter design software for Hybrid HVDC

2020 IEEE 1st China International Youth Conference on Electrical Engineering (CIYCEE), 2020
With the increasing capacity and transmission distance of the power grid, HVDC technology has been more and more widely used. MTDC is an essential direction for the development of HVDC technology. At this stage, LCC is widely used in the MTDC transmission project, and there is a lot of corresponding design software, but the software development of the ...

Efficient modeling of hybrid MMCs for HVDC systems

2017 IEEE Energy Conversion Congress and Exposition (ECCE), 2017
Modular multilevel converters (MMCs) have become the most promising converter technologies for medium/high-power applications, specifically for high-voltage direct current (HVDC) transmission systems. For the analysis of the large-scale MMCs-embedded power systems, i.e., multiterminal dc (MTDC) systems and dc grids, modeling and simulation plays an ...

Hybrid HVDC system for multi-infeed applications

2013 International Conference on Emerging Trends in Communication, Control, Signal Processing and Computing Applications (C2SPCA), 2013
The application of HVDC for stabilizing the large interconnected AC networks are resulting in several HVDC links inverting in the close electrical proximity. These multi-infeed HVDC system inverting into a weak AC network are of serious concern. One of the possible solution for better stability is using a VSC-HVDC as one of the infeed for the multi ...

Fullbridge MMC control for hybrid HVDC systems

2017 Brazilian Power Electronics Conference (COBEP), 2017
The Fullbridge based Modular Multilevel Converter (FBMMC) has been widely considered as one of the best solutions for High Voltage Direct Current (HVDC) systems, especially due to its capability of limiting dc short-circuit currents. Generally, the use of FBMMC on hybrid HVDC configurations with Line Commutated Converters (LCC) is considered for ...
