Abstract

In this paper measurement results from a low voltage microgrid test facility are presented and analyzed using a black box modeling methodology based on Prony analysis. Several test cases are investigated with the microgrid operating in grid-connected and islanded mode, including step changes in loads and distributed generation units. The black-box modeling methodology is applied to the measurement results and can provide information considering the amplitude, the frequency and the damping of the oscillations appearing in the microgrid responses. Results show that the black-box model can represent with good accuracy the dynamic behavior of the microgrid.
