This document presents a statistical approach to conducting large experiments based on statistical analysis to determine the most significant influence of multiple factors involving inverter-based islanded AC microgrids. Since there is no formal method in microgrid applications that integrates multiple elements further control strategies while several data are statistically analyzed, the Design of Experiments theory was applied. The analysis considered more factors rather than evaluating each one separately. An microgrid testbed was used to perform the experiment. The approach to analyze interest variables regarding power-sharing and power quality was through inverters, passive filters, hierarchical control strategies, and PWM techniques. This microgrid was previously validated in hardware-in-the-loop simulation. In addition, a control-program and a human-machine-interface were designed to conduct all the configurations. The experimental results and the statistical analysis identified the factors and interactions between factors that mainly affect the operating conditions of the MG in terms of quality and power-sharing.
