Smart grid accommodation of distributed generation for more reliable quality of supply

Installation of a large number of small sources called distributed generation creates many problems in proper control of national (and European) power grid. At the same time new technologies especially power electronics and measurement data computing associated with smart grid allows to use better and conscious these distributed sources. This paper describes what problems the distributed generation may cause, how this is mitigated and how the smart grid approach may take advantage of specific characteristic of distributed sources for ensuring more reliable quality of supply.
