Call for papers: "Advanced Power Electronic Systems for HVDC and DC Grids"

For a special issue of the International Journal of Power Electronics.

Increasing demand for electricity has led to continuously increased renewable energy sources integration as sustainable alternatives to large fossil fuel driven central power plants. This calls for more long distance power transmission, and increasingly high-voltage direct current (HVDC) instead of ac transmission is used for this purpose. The application of HVDC converter technology in power grids is growing very fast. They were initially introduced based on line-commutated semiconductor technologies (Classic HVDC) and more recently based on self-commutated semiconductor technologies (Voltage-source converter (VSC) HVDC). Recent developments in power electronic converter systems have undergone a rapid evolution where different topologies of VSC HVDC have been introduced to this market.
The high level of modularity and low losses of modular multilevel converters (MMC) have made them more attractive for HVDC applications, in comparison to previous schemes. However, the efficiency, cell capacitor voltage ripple and dynamic performance are three contradictory aspects of the MMC which are related to the converter topology and control scheme. Therefore, there are several alternative power electronic converter configurations under rapid research and development at various manufacturers and research centers which require substantial evaluation in terms of system operation, control and valve implementation to optimise costs and losses. In addition to the steady state operation, robust transient fault handling is a crucial issue where the further development of overhead line VSC HVDC, multi-terminal HVDC and DC grids are considered for the future dc transmission grid. There is a need for reliable and cost-effective solutions for handling internal and external faults in power electronics based HVDC Transmission systems are the other recent research challenges in this area.
Power electronic converter systems in HVDC systems is a very timely topic for power electronic and power system researchers all around the world. The objective of this special issue in is to attract quality submission addressing the various aspects of the advances of power electronic systems in HVDC applications.
Suitable topics include, but are not limited, to the following:
  • MMC and other emerging power topologies of HVDC converters
  • Alternate cells for MMC
  • Converters for new applications of HVDC
  • Modeling and analysis of HVDC converters
  • Modulation and control of HVDC converters
  • Design and protection of HVDC converters
  • Inner control issues and methods of MMC and other HVDC converters
  • New semiconductors technologies for HVDC converters
