A deterministic analysis method for back-feed power restoration of distribution networks

Abstract

This paper presents a deterministic algorithm that identifies a back-feed restoration strategy to restore the out-of-service load due to fault isolation while ensuring that the post-restoration network has a valid configuration. The algorithm is based on the concepts of network tracing and it supports both single-path and multi-path restoration. In case the network components are too stressed and even the multi-path restoration cannot restore all the out-of-service loads, the algorithm tries to shed minimal load while restoring as many other loads as possible. Capability of the algorithm is demonstrated with a few back-feed restoration solution examples.
