TLDR
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.Abstract:

Fault Current Interruption by the Dynamic Voltage Restorer
TL;DR: In this paper, an auxiliary control strategy for downstream fault current interruption in a radial distribution line by means of a dynamic voltage restorer (DVR) is introduced and evaluated, and the results of simulation studies performed in the PSCAD/EMTDC software environment indicate that the proposed control scheme can limit the fault current to less than the nominal load current and restore the point of common coupling voltage within 10 ms.
