Abstract
The observability needs in future power systems will
change radically due to the continuing implementation of
renewable energy sources at all voltage levels. Especially in
distribution grids new observables will be needed in order to
monitor the state of the power system sufficiently and to perform
the correct actions for operating the system. In future power
systems more measuring sensors including phasor measurement
units will be available distributed all over the power system. They
can and should be utilized to increase the observability of the
power system. In this paper the impact of photovoltaic and wind
power production on the voltage unbalance was analyzed. PMU
data and NTP-synchronized data from two different MV networks
were used. It has been found that PV production has only a minor
negative impact on the voltage unbalance whereas the wind power
production has a great positive impact. The voltage unbalance
factor (VUF) could be a ‘new’ observable for a particular power
system condition. Information about the actual injected wind
power for a certain grid area could be derived without
knowing/measuring the real wind power injection.
