Analysis of the impact on voltage due to the massive connection of distributed generation to reduce electrical interruptions in densely populated areas

Abstract

This study has focused on the implementation of distributed generation to reduce the number of power cuts in densely populated areas, due to its possible benefits that have been published by some researchers. The implemented methodology seeks to determine an adequate percentage of DG penetration to solve electrical interruption problems caused by low voltage levels. Therefore, the power flow simulations will be performed by implementing the ETAP power system analysis software, using the IEEE 34-node test system. The process will be carried out through different DG penetration scenarios, to finally analyze the results based on the voltage and power parameters, which allow studying the quality of energy and the increases in energy losses of the electrical networks. The main results obtained are directly related to the level of DG penetration where, when applying the same amount of DG in the four study areas, it was observed that in order to determine the percentage of DG penetration, it is necessary to find the areas with the greatest effect on the, which in this case was the one with the lowest voltage level, causing the greatest increase in current and obtaining a considerable percentage, but complying with the established parameters. This research lays the foundations for the integration of DG at the medium voltage distribution level, for which future work is proposed on the study at the low voltage distribution level.
