In a DC grid, contingencies such as converter outages give rise to a current imbalance that
is reflected in the DC node voltages in the grid. This imbalance has to be accounted for by …

The number of semiconductor switches in a modular multilevel converter (MMC) for HVDC
transmission is typically two orders of magnitudes larger than that in a two or three level …

This paper discusses the extension of electromechanical stability models of voltage source
converter high voltage direct current (VSC HVDC) to multi-terminal (MTDC) systems. The …

With the rapid increase of renewable energy sources and power electronic converters in the
power system, the inertia of the power system is declined and the stability problem is more …

Abstract Modular Multilevel Converters (MMC) are presently the converter topology of choice
for Voltage Source Converter High Voltage DC (VSC-HVDC) transmission schemes due to …

Three configurations of voltage source converter multi-terminal HVDC transmission for large
offshore wind farms are studied. The voltage-current characteristics of the converters are …

This paper analyzes the influence of the converter droop settings and the dc grid network
topology on the power sharing in a dc grid based on voltage source converter high voltage …

With the advance of power electronic technology, the application of HVdc light systems
based on voltage-source insulated gate bipolar transistor (IGBT) converters has increased …

This paper addresses the possibilities to exchange primary reserves within a multi-terminal
HVDC (MTDC grid) system as well as between asynchronous ac grids connected through …

VSC-HVDC systems are being increasingly employed in the power systems. The recently
installed HVDC systems have a power capacity similar to traditional power plants. Hence …
