microgrids have recently attracted attention from academic and industrial
research since they offer a multifunctional and efficient way to locally
interconnect energy resources as well as loads. By applying the DC link voltage
as an ubiquitous accessible parameter for all components, defined low-flow
conditions both under grid-tied and islanded operation can be realized using
voltage droop curves. However, due to lacking system inertia stabilizing
conventional AC grids, stability of a DC microgrid entirely depends on the
control loop setup and grid-side passive components of its power electronic
converters. In the following, the passivity-based stability criterion is
selected as design basis. A simple analytical way to set up droop-controlled
power electronic converters for stable grid operation is introduced. Lastly,
the chosen approach is verified in a practical trial by complex impedance
measurements using pseudo-random test signals.
