This paper introduces the application of intelligent agents to the control and operation of distribution systems that contain distributed generators (DCs). The proposed control architecture is hierarchical with one supervisor that optimizes the overall process and a distributed number of local control agents associated with each DG. Control and protection actions need a fast reaction time and are taken by the control agents. They consist of fixed sets of parameters. Coordination, modifications of the criteria and parameters for the control and protection equipment, are performed at the control center. The proposed intelligent control agent based architecture is illustrated using a test system with two microturbines as DCs.
