Optimal Overcurrent Relay Coordination: A Review
Procedia Engineering, 2013 AbstractThis paper presents an overview on optimal overcurrent relay coordination in protection system and protective relays. Efforts have been made to include all methods used for the coordination of overcurrent relays. It includes techniques, such as Artificial Intelligence (AI) and Nature Inspire Algorithm (NIA) as well as other conventional methods

2012 IEEE International Symposium on Information Theory Proceedings, 2012 In this paper, we study the problem of coordinating two nodes which can only exchange information via a relay at limited rates. The nodes are allowed to do a two-round interactive two-way communication with the relay, after which they should be able to ...

Optimal coordination of overcurrent relays for microgrid operation using JAYA algorithm
e-Prime: Advances in Electrical Engineering, Electronics and EnergyIn modern microgrids, relay coordination is a very tedious task because of the variation in magnitude and direction of fault current. The change in fault current is diverse for inverter interfaced DGs (IIDGs) and synchronous-based DGs (SBDGs) The ...

Coordinating mRNA maturation: The U1 relay model. [PDF]
Mol CellmRNA maturation requires precise coordination among transcription, 5' capping, splicing, and 3' end formation. Recent biochemical, structural, and genomic studies demonstrate that these processes are tightly coupled through dynamic interactions among RNA polymerase II, the spliceosome, and cleavage-polyadenylation complexes. Here, we synthesize current
