A multi-objective distribution network reconfiguration and optimal use of distributed generation unites by harmony search algorithm

Abstract

In this paper, the method of network reconfiguration and simultaneous use of distributed generation resources (DG) in optimal location and capacity is analyzed in order to minimize losses and reach the optimum level of voltage stability and voltage profile. A new method for this purpose is proposed by use of the Harmonic Search Algorithm (HSA). To investigate the effectiveness of the proposed method, the capabilities of the MATLAB software and the DPL language linked to the DIGSILENT application is used. The 33-node distribution network of IEEE standard was selected for investigation. The simulation results shows that by using the proposed method, network losses were minimized and the voltage level and voltage profiles were improved correctly.
