Autonomous Load Shedding in a Nanogrid using DC Bus Signalling

John Schonberger, Simon Round, Richard Duke
2006 Industrial Electronics Society (IECON ), Annual Conference of IEEE  
Autonomous load shedding can be implemented in a nanogrid that uses DC bus signalling for source scheduling by shedding loads when the dc bus voltage decreases to a level that signals an overload condition  ...  Including load shedding in the system control strategy for a small standalone hybrid power system such as a nanogrid is beneficial since the peak generation requirement is reduced and the system is protected  ...  Two such hybrid strategies are hybrid central and hybrid distributed control.  ...
