An multi-agent approach to protection relay coordination with distributed generators in industrial power distribution system

This paper presents new explorations into the use of agent technology applied to protection coordination of power systems. The impact of distributed generators on protection coordination is firstly discussed. Then a coordination multi-agent system is proposed with the functions of the agents described. In the proposed system, communication plays an important role to provide more information for the relay coordination besides the relay settings. Communication simulation has been carried out on the Java agent development framework (JADE) platform. The information communication process shows that adaptive coordination can be achieved.
