Modeling and Simulation of Three-Phase AC Microgrid

Abstract

Sustainable power at the forefront of Department of Defense operations is paramount on the battlefield as well as at naval installations around the world, and microgrid technology enables the deployment of renewable energy sources. This thesis develops a physics-based model of a three-phase microgrid set up with three commercial-off-the-shelf (COTS) inverters and a battery bank as its energy storage system. Both the model and the laboratory microgrid can be operated in grid-tied or in islanding mode. The microgrids voltage waveforms, spectra, total harmonic distortion, and current waveforms are predicted by simulations and measured in the laboratory. IEEE Standard 519 and the manufacturers performance standards provide the metrics for the power quality analysis. Comparisons of performance of the model to experimental laboratory data determine that the COTS units conform to IEEE Standard 519 and are suitable for further studies into microgrid expansion, management, and employment.
