Abstract

This paper introduces the Harmony Search (HS) algorithm to solve the distribution network minimum loss reconfiguration problem. The HS is an emerging music-based meta-heuristic optimization algorithm. It is a population-based approach which mimics musicians' behaviors such as random play, memory-based play, and pitch-adjusted play when they perform improvisation. The HS algorithm is simple in concept, less in parameters, and easy in implementation. The optimization problem is formulated taking into account the operational constraints of the distribution systems. Results of numerical tests carried out on a 69-bus system from literature are presented to show the effectiveness of the proposed approach.
