Abstract: This paper presents a new method to solve the network reconfiguration problem in the presence of distributed generation (DG) with an objective of minimizing real power loss and improving voltage profile in distribution system. A meta heuristic Harmony Search Algorithm (HSA) Algorithm is used to simultaneously reconfigure and identify the optimal locations for installation of DG units in a distribution network. Sensitivity analysis is used to identify optimal locations for installation of DG units and also Different scenarios are used. The constraints of voltage and branch current carrying capacity are included in the evaluation of the objective function. Here both HSA and PSO methods are used that has been tested on 33-bus and 69-bus radial distribution systems at three different load levels to demonstrate the performance and effectiveness of the HSA and PSO methods. The results obtained are encouraging.
