Distributed Generators units and shunt capacitors are allocated and sized optimally and simultaneously for line loss reduction, voltage profile improvement and the reliability rising of the power system. The objective function which includes power losses (active and reactive), voltage profile and reliability indices is maximized using genetic algorithm. Power system operation limits are considered as constraints. The problem of optimal distributed generation and capacitor sizing and placement is solved for a 9-buses test system and the results of applying the proposed method illustrate the best answer is found by optimizing both DGs and capacitors in distribution networks
