Service Restoration in Distribution Systems under Different Load Levels

Abstract

This paper addresses with a modified sequential opening of branches (MSOB) method to service restoration under different load levels as self-healing distribution systems. This MSOB reduces the search space of the optimization to search for executed tie-switches and sectionalizing switches based on defined loop configuration in systems. To observe the effectiveness of the proposed method, the standard IEEE 33-bus and 69-bus distribution systems are selected to be tested. The optimal solutions with computation time are provided in this paper.
