Multi-agent application in protection coordination of power system with distributed generations

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 the relay coordination besides the relay settings. Relay coordination strategy is also discussed and communication simulation between different substations has been carried out on Java Agent Development Framework (JADE) platform. The simulation results show that proper protection coordination can be achieved by the proposed coordination strategy and information communication.
