Technical feasibility of Power Flow Controllers for HVDC grids
Power Flow Controllers (PFCs) or Current Flow Controllers (CFCs) are expected to be required in future High Voltage Direct Current (HVDC) grids.
Optimal Sizing on a Mission Profile of Isolated NPC DC-DC Converters using 3.3 kV SiC MOSFETs for Power Electronic Traction Transformers
A reduction of 13 % of the total energy loss on a typical journey can be obtained by optimising the design of the DC/DC converter on a mission profile rather than at nominal power.
Differential Flatness-Based, Full-Order Nonlinear Control of a Modular Multilevel Converter (MMC)
The main interest of this Full-Order Nonlinear Control is the possibility to obtain a very high dynamic performance of the MMC power flow.
Understanding the role of VSC control strategies in the limits of power electronics integration in AC grids using modal analysis
In this article, the interactions between AC grid and existing VSC control modes are analyzed.
Pre-energization concept for overhead lines in MTDC grids using DC Circuit Breakers internal capacitor
This paper proposes an auxiliary circuit for mechanical type DC Circuit Breakers which enables to use the internal energy of the DCCB capacitor for the line pre-energization.
