Service Restoration in Distribution System Using Breadth-First Search Technique

Abstract

When a fault occurs in the Radial Distribution System, it may take some time to repair the faulted section, and there is no supply to the rest of the sections which are connected to the faulted section until it is repaired. Therefore, the problem of service restoration is an important task in distribution systems. Service must be restored to out-of-service areas by connecting the isolated sections to the other feeders. This can be done by changing the status of the switches between the zones. The generalized algorithms for the problem of service restoration in distribution systems during a fault at a particular zone were developed using Breadth-First Search are tested on a practical test distribution system. The effectiveness of the proposed Breadth-First search method in terms of computational burden is the efficacy of the presented strategy.
