Abstract:
|
This paper presents a networked control scheme for
a photovoltaic-based industrial microgrid to adaptably operate in
both grid-connected and islanded modes, and even to transfer
smoothly between these two modes. The control scheme is mainly
based on the droop method for active and reactive power sharing
by means of voltage and frequency regulation. In addition, to get
a smooth transfer between islanded and grid-connected modes, a
phase-locked loop is also used in the control system. This loop is
only activated during islanded mode to eliminate the phase
deviation between the voltages in both sides of the point of
common coupling switch. The output of this loop is send to all
power units following a one-to-all communication scheme with low
bandwidth. Finally, selected simulation results are reported in
order to prove the effectiveness of the control scheme. |
