Time synchronized low-voltage measurements for Smart Grids

Abstract

This paper deals with possible future development of Smart Grids based on more detailed monitoring of grid. The aim of this work is to propose measurements for low-voltage level of Smart Grids inspired by measurements known from high-voltage level. Using time synchronization and intelligent endpoint devices creates wide area measuring grids to collect essential data for faster detection of illegal consumers, branch overload detection, power-quality verification, and other features. These can improve overall stability and reliability of grid by covering low-voltage level that is typical with dynamic change of topology, different sources of disturbances and as primary source for majority of customers.This paper deals with possible future development of Smart Grids based on more detailed monitoring of grid.
