Implementation of firefly algorithm for distribution system reconfiguration with reliability evaluation

Abstract

This paper is about a meta-heuristic optimization method. i.e. Firefly Algorithm (FA) implemented to find the optimal configuration for Radial Distribution Network (RDN). Distribution System Reconfiguration (DSR) improves the performance of RDN with improved voltage profile and minimizing the power loss. The reliability indices such as System Average Interruption Frequency Index (SAIFI) and Average Energy Not Supplied (AENS) are calculated to evaluate distribution system reliability. Four different cases are studied on the system to analyze the performance: i) with no DG and DSR, ii) with DG but no DSR, iii) with DSR but no DG, vi) with DSR and DG, on IEEE 33-Bus test system and local 10-Bus Arilova SS (Distribution Sub-Station) using Matlab.
