Grid simulator for power quality assessment of micro-grids

Abstract: In this study, a grid simulator based on a back-to-back inverter topology with resonant controllers is presented. The simulator is able to generate three-phase voltages for a range of amplitudes and frequencies with different types of perturbations, such as voltage sags, steady-state unbalanced voltages, low-order harmonics and ﬂicker.

Microgrid Control

A microgrid can operate when connected to a utility grid (grid-connected mode) or independently of the utility grid (standalone or islanded mode). In islanded mode, the system load is served only from the microgrid generation units. In this mode, the microgrid control regulates voltage and frequency of generation units using grid-forming control.
