This paper proposes a Multi-agent System (MAS) approach to coordinate overcurrent relays, aiming to protect distribution systems with distributed generators. The connection of distributed generation (DG) units causes a reduction in the efficacy of protection systems coordination and, in some cases, an increase of operating times. Coordination studies aim to guarantee the protection selectivity in...
This paper presents new explorations into the use of agent technology applied to the protection coordination of power systems. The impact of distributed generators on protection coordination is first discussed. Then, a coordination multiagent system is proposed with the functions of the agents described. In the proposed system, communication will play an important role to provide more information...
Anti-islanding protection schemes currently enforce the DGs to disconnect immediately for grid faults through loss of grid (LOG) protection system. This greatly reduces the benefits of DG deployment. For preventing disconnection of DGs during LOG, several islanding protection schemes are being developed. Their main objectives are to detect LOG and disconnect the DGs from the utility. This allows the...
This paper presents new explorations into the use of agent technology applied to substations protection coordination of power system. The impact of distributed generation on protection is firstly discussed. Then a coordination multi-agent system is proposed with the functions of the agents described. In the proposed system, communication will play an important role to provide more information for...
