Impact of Green Power Distributed Generation to Voltage Profile and Protection Issues by Different Penetration Levels - A Study Developed on ATP Draw

Abstract

The connection of distributed generators in distribution systems of medium voltage or low voltage has been encouraged widely. Thus, it is necessary to assess the impacts and contributions to the voltage profile, as well as possible changes in the magnitudes of the short-circuit current and the consequent correlation with the adjustment of protection. This article investigates a feeder voltage profile through three different system load levels and evaluates the influence of the penetration level of a distributed generator. The results are compared in tables providing the reader a better insight into the issue discussed here.
