Multi Objective Optimization Placement of DG Problem for Different Load Levels on Distribution Systems with Purpose Reduction Loss, Cost and Improving Voltage Profile Based on DAPSO Algorithm

Abstract

Along with economic growth of countries which leads to their increased energy requirements,<br />the problem of power quality and reliability of the networks have been more considered and<br />in recent decades, we witnessed a noticeable growing trend of distributed generation sources<br />(DG) in distribution networks. Occurrence of DG in distribution systems, in addition to<br />changing the utilization of these systems, has provided the opportunity for these companies to<br />be able to design systems with lower costs. In this paper, the problem of placement and<br />capacity determination of DG were carried out using multiple methods. The main objectives<br />of issue were improving the voltage profile, losses reduction and reduce the cost of operation<br />that were carried out based on an economic function. Using the multiple methods to improve<br />some purposes and utilization of weighting coefficients provided an appropriate plan.<br />DAPSO algorithm was used for optimization and various experiments carried out on real<br />network.
