Harmonic analysis of microgrid operation in islanded mode with nonlinear loads

Renewable energy sources are being incorporated into power grids across the globe. These sources are integrated either in the form of microgrids or distributed energy sources. However microgrids are gaining better attention as it facilitate the consumers to utilize power from utility grid as well as renewable energy sources. Hence microgrids can operate in grid connected mode or islanded mode. This paper analyzes impact of nonlinear loads in a microgrid in terms of power quality. Harmonic distortion in microgrid voltage profile is considered for the study. It is recognized from the study that increase in the number of distributed renewable sources facilitate reduction in total harmonic distortion (THD) in buses.
