Flexible Control of Power Flow in Multiterminal DC Grids Using DC-DC Converter

This paper proposes an efficient control framework that utilizes de-de converters to achieve flexible power flow control in multiterminal de (MTDC) grids. The de-de converter employed in this paper is connected in cascade with the de transmission line, and is therefore named cascaded power flow controller (CPFC). In this paper, a two-layer control strategy is developed for the operation and con...

DC-DC Power Converters

Dc-dc power converters are employed in a variety of applications, including power supplies for personal computers, office equipment, spacecraft power systems, laptop computers, and telecommunications equipment, as well as dc motor drives. The input to a dc-dc converter is an unregulated dc voltage Vg. The converter produces a regulated output voltage V, having a magnitude (and possibly polarity...

AC versus DC Power Distribution in the

Low Voltage DC Distribution System

AC distribution is conventional and its future is now under threat with its major competitor DC distribution. Transformer voltage conversion can be replaced completely by DC-DC converter in DC distribution with voltage and current regulation. DC energy and energy saving as the distribution match well with the recent technology in renewables, energy storage, computer and control electronics, mod...

Enhancement of Power Quality in Grid Integrated System using DC-link Voltage PI Controlled VSC based Statcom

This paper demonstrates an enhancement of power quality in grid integrated systems with the help of the proposed control strategy for voltage source converter based active power filters. The Shunt Active Power filters (SAPF) are extensively utilized in modern grid integrated systems to diminish the power quality concerns associated with it. The SAPF is one of the various power filters, which ha...
