Constructive back-feed algorithm for online power restoration in distribution systems

The paper proposes a simple yet effective back-feed restoration algorithm to reinstate supply to the loads following a distribution system fault. The algorithm tries to balance the load served by the individual substations in the post fault restoration strategy. The proposed algorithm is essentially a constructive network tracing algorithm which comes up with final network restoration strategy by determining the switching sequences of the feeder switches like circuit breakers, sectionalizers, etc. Simple example systems are considered to demonstrate the algorithm. The algorithm is considered to be applicable to the smart grids in which reliability of the supply is a major concern.
