Multi‐agent application of substation protection coordination with distributed generators

This paper presents new explorations into the use of agent technology applied to substation protection coordination of power systems. The impact of distributed generators (DG) on protection coordination in substation with different locations is discussed first. 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 has been carried out on the Java agent development framework (JADE) platform. The simulation results shows that proper protection coordination can be achieved by the proposed coordination strategy and information communication.
