How facts on the distribution system are being used to improve power quality

Abstract

Flexible AC transmission systems, which use power electronic, based on controllable systems for transmission systems can now be scaled for use on the distribution system. Solutions like this can mitigate the source of distribution power quality (PQ) problems while providing an inherent PQ improvement to other customers on the connected network. In the last decade, commercial electric customers have become increasingly interested in the relative 'quality' of the power they purchase. Although it may be difficult to imagine that some supplies of electricity can be better than others, variations in the flow or the voltage can actually damage and disrupt sensitive electronics, computers, and microprocessors. As businesses rely more heavily on modern high-tech processes, PQ is becoming even more important.
