Abstract

A power router has been recently developed for both AC and DC applications that has the potential for smart-grid applications. This study focuses on three-phase power switching through the development of an experimental setup which consists of a three-phase direct AC/AC matrix converter with a power router attached to its output. Various experimental switching scenarios with the loads connected to different input sources were investigated. The crescent introduction of decentralized power generators throughout the power-grid obligates us to take measurements for a better distribution and management of the power. Power routers and matrix converters have great potential to succeed this goal with the help of power electronics devices. In this paper, a novel experimental three-phase power switching was achieved and the advantages of this operation are presented, such as on-demand and constant power supply at the desired loads.

Highlights

Distribution power-grids are undoubtedly one of the most complex systems humanity has ever created.Their structural vulnerability is a crucial factor [1] and the introduction of smart-grids and renewable energy sources has increased the difficulty of the analysis [2] since many parameters have to be taken into consideration in contrast with the straight-forward classic power supply
It is obvious that power management is necessary in order to perform an effective power routing of this vast amount of newly incorporated renewable resources
This paper demonstrates a novel three-phase power routing

Summary

Introduction

Distribution power-grids are undoubtedly one of the most complex systems humanity has ever created Their structural vulnerability is a crucial factor [1] and the introduction of smart-grids and renewable energy sources has increased the difficulty of the analysis [2] since many parameters have to be taken into consideration in contrast with the straight-forward classic power supply. This increase in complexity requires new methods of power routing.
