A novel voltage stability indicator for loss minimization in distribution system using reconfiguration [articol]

Abstract

This paper presents a novel technique for loss minimization in distribution systems with a voltage stability indicator (VSI). A new VSI is modeled by considering distribution system losses. This VSI is used to improve the system stability parameters, reduce distribution loss and to find the maximum loadability limit of the various distribution conductors. Network reconfiguration is implemented using minimum brach current method and minimum voltage difference method. The proposed technique is tested on IEEE 33 bus and an India real time system of 62 bus using MAT LAB software environment. The simulation results are presented to demonstrate the effectiveness of the proposed VSI.
