Placement of Distributed Generation Unit and Capacitor Allocation in Distribution Networks In Order To Reduce Losses and Develop Voltage Profile Using Genetic Algorithm

This paper is aimed at investigating optimal placement of DG and capacitor in radial distribution systems in order to reduce losses and enhance voltage profile. Simulation is done using genetic algorithm to minimize loss of active power, loss of reactive power and to enhance voltage profile and multipurpose optimization. In this study, at first the effect of placement of DG and capacitor is evaluated separately and then it is investigated synchronously. With regard to synchronic placement two conditions are examined: 1) all equipments are embedded on a same bus. 2) Equipments are placed on different buses. Load flow is done according to RaphsonNewton method. Simulation conducted on the two standard networks 33 and 69 bus IEEE is tested. Results indicate that losses are reduced significantly and voltage profile is enhancing also.
