Intelligent Agent for Smart Grid Fault Location Isolation using Simulink

In this paper, implementation of fault location isolation for self-healing power distribution system in smart grid using intelligent agent approach is presented. Self-healing grid is an important feature in smart grid. Distributed techniques that handle complexity of fault location isolation and service restoration algorithms eliminate centralized decision making and computational burden allowing faster response, which increase system reliability in an electric grid. For this reason, multi-agent system is one of the most suitable approaches for applying fault location isolation and service restoration algorithms. Every agent is configured to be fully autonomous and distributed having their design objective. A hierarchal architecture for multi-agent system is proposed for less communication burden. Every agent can communicate with neighbor agents within same level or a higher level parent agent. When fault occur, every zone agent read and exchange measured data with neighbor agents. Agent that observe a higher change in measured data will isolate fault and send isolated fault location to feeder agent for restoration decision process.
