Voltage sag distributions caused by power system faults
Pirjo Heine,Matti Lehtonen +1 more
TL;DR: In this paper, the authors established voltage sag distributions caused by faults at different voltage levels and experienced by low-voltage customers for four different power system areas, and the shares of different fault types at each voltage level and the sag propagation throughout the power system were taken into account.

Introducing custom power
TL;DR: The concept of custom power is now becoming familiar as mentioned in this paper and it describes the value-added power that electric utilities and other service providers will offer their customers in the future The improved level of reliability of this power, in terms of reduced interruptions and less variation, will stem from an integrated solution to present problems, of which a prominent feature will be the application of power electronic controllers to utility distribution systems and/or at the supply end of many industrial and commercial customers and industrial parks.
