Service restoration strategy for active distribution networks considering source-load uncertainty

International Journal of Electrical Power & Energy Systems
Active distribution networks (ADNs) incorporate numerous distributed generations (DGs) and energy storage systems. When sudden faults occur in the system, service restoration can be enhanced through microgrid formation and network reconfiguration ...

Fault-tolerant static scheduling for grids

2008 IEEE International Symposium on Parallel and Distributed Processing, 2008
While fault-tolerance is desirable for grid applications because of the distributed and dynamic nature of grid resources, it has seldom been considered in static scheduling. We present a fault-tolerant static scheduler for grid applications that uses task duplication and combines the advantages of static scheduling, namely no overhead for the fault ...
