Modeling and Control of AC Microgrids Under Unbalanced Utility Grid Voltage Using the Invariant-Ellipsoid Method

IEEE Access
The increasing penetration of renewable microgrids (MGs) into utility grids (UGs) has introduced new stability and power quality challenges, especially under the unbalanced voltage of the utility grid.

Weighting function integrated in grid-interfacing converters for unbalanced voltage correction

RE&PQJ
In  this  paper  a  weighting  function  for  voltage  unbalance  correction  is  proposed  to  be  integrated  into  the  control  of  distributed  grid-interfacing  systems.  The  correction  action  can  help  decrease  the  negative-sequence  voltage  at  the  point   of   connection   with   the   grid.
