Adaptive Harmony Search Algorithm for Optimal Network Reconfiguration

doi:10.11930/j.issn.10.11930.2015.4.131

Abstract

Abstract: The harmony search algorithm(HSA) is affected by initial parameter values when it is used to search the optimal scheme for distribution network reconfiguration. Therefore, an adaptive harmony search algorithm(AHSA) is proposed and improved by adding local search, thus enhancing the optimization performance of the algorithm. A mathematical model of distribution network reconfiguration is built for the purpose to reduce the active and reactive power loss, and a load flow calculation is made for the network with the forward and back/forward substitution method based on node-layer. The IEEE 69-bus radial distribution system is simulated and the simulation result is compared with that calculated with the harmony search algorithm and genetic algorithm (GA), which shows that the proposed algorithm has less iterative times and better convergence effect. The adaptive harmony search algorithm is proved feasible through its application in distribution network reconfiguration.

Key words: harmony search algorithm, network reconfiguration, initial parameter value, adaptive harmony search algorithm, local search, active and reactive power loss, load flow calculation
