Abstract (EN):
Under normal operating conditions, a MicroGrid
(MG) is interconnected with the Medium Voltage (MV) network.
However, planned or unplanned events like maintenance or
faults in the MV network, respectively, may lead to MG
islanding. In order to deal with islanded operation and even
black start following a general blackout, an emergency operation
mode must be envisaged. Two possible control strategies were
investigated and are described in this paper in order to operate a
MG under emergency mode. A sequence of actions for a well
succeeded black start procedure, involving microgeneration
units, has also been identified contributing for an increase in
distribution network reliability.
