Hybrid multi agent approach for power distribution system restoration

In this paper a hybrid multi agent system approach for fast power restoration in power distribution systems is presented. Hybrid structure of MAS provides the capability of solving the restoration problem with taking the advantages of both centralized and distributed agent structures. Bottom-up order of agents constructing the MAS is zone agents, feeder and substation agents. In this architecture, agents have the permission to execute a function based on their hierarchy level and the control central supervisory is not always required. After the fault location and isolation, agents start communicating with their higher level agents to initiate the reconfiguration and restoration plans. According to the algorithm, agents try to restore the un-faulted zones as much as possible considering the restoration constraints. An existing Mon Power distribution system with 5 feeders is selected for computer simulation to test the effectiveness of proposed approach. The simulation results show that the proposed multi agent approach is effective and promising.
