Enhancing Recloser-Fuse Coordination Using Distributed Agents in Deregulated Distribution Systems

This paper introduces a new adaptive scheme to avoid miscoordination associated with recloser-fuse protection of distribution network under distributed generation insertion. The proposed technique exploits the distributed agents embedded in the smart grid to adapt the time dial setting of the fast curve of the recloser. The distributed agents are located at fuses points to transmit the required fuse current during fault conditions to the recloser. Also, the presented method is compared with different existed algorithms. Response of the presented scheme is assessed under various scenarios by simulating an actual Egyptian 11 KV overhead distribution feeder using Matlab/Simulink package. Sample results are evaluated and examined.
