Recently, the electric utility industry in the whole world has been facing pressure to be deregulated or restructured in order to increase its efficiency, to reduce operational cost or to give consumers more alternatives. For this aspect, a great deal more research is needed to achieve better intelligent knowledge process. The present centralized system for the power system control, operation and planning must be remodeled to cope with these situations. With the promotion for the deregulation of the electric power system, the definition of the objective function for the optimization problem such as outage work operation for electric power system is becoming critical. Currently, agents are focus of intense on many sub-fields of computer science and artificial intelligence. Agents are being used in an increasingly wide variety of applications.
In this paper, we developed a power system normal operation application by multi-agent architecture. Our multi-agent system consists of several Facilitator-agents, Equipment-agents and Switch-box-agents. Facilitator-agent acts as a manager for negotiation process between agents. Equipment-agent corresponds to the element of the electric power system, such as bus, transformer and transmission line, while Switch-box-agent is the pseudo object which consists of neighboring current breakers and disconnecting switches. The proposed system realizes the appropriate switching operations by interacting with corresponding agents. The proposed approach is applied to a simple network, and the results show that the proposed multi-agent system is an efficient decentralized approach for solving power system normal operations.
