Abstract
Voltage quality is becoming more and more important in
distribution grids, not at least in Norway that has a large
share of weak grids. Although voltage monitoring is not
mandatory when smart meters are rolled out in Norway
in 2019, it gives an excellent opportunity to gain a huge
improvement in observability of the distribution grid.
Measurements from smart meters can amongst others be
used to monitor for dangerous faults that today can go on
undetected for a long period of time. Voltage monitoring
can also, by using a small amount of statistical data, give
an in depth overview over the available voltage margins
in all parts of the grid, and to uncover parts of the grid
that need reinforcement. It can also be useful for
handling customer complaints.
