Application of graph theory for automatic restoration distribution networks

Abstract:
The modern concept of a distribution network implies an expansion of the possibilities of using various digital devices to solve the assigned tasks. One of these tasks is to reduce the time during which consumers, as a result of fault in the network, remain without power. To solve this problem, the use of the fault location, isolation and service restoration (FLISR) complex is becoming more and more popular. This complex consists of many algorithms, but the service restoration is the most important one. In order to restore power to the largest number of consumers while preserving the radial structure of the network, graph theory can be used as a tool to find the most optimal network topology. The purpose of this article is to consider the basics of FLISR, as well as the potential use of graph theory as a tool for modifying the service restoration algorithm.
