Supporting transient stability in future highly distributed power systems [PDF]

, 2010
Incorporating a substantial volume of microgeneration (consumer-led rather than centrally planed) within a system that is not designed for such a paradigm could lead to conflicts in the operating strategies of the new and existing centralised generation ...

Topologically Protected Loop Flows in High Voltage AC Power Grids

, 2016
Geographical features such as mountain ranges or big lakes and inland seas often result in large closed loops in high voltage AC power grids. Sizable circulating power flows have been recorded around such loops, which take up transmission line capacity ...
