Abstract
Power quality
problems constitute a headache for power systems engineers. The detection and
mitigation of these problems increases the reliability and availability of the
system. Phasor measurement units are devices introduced to assess the health of
the power system. Furthermore, renewable energies turn out to be not only
sources of energy but can be used as medicines to the power quality problems as
well. In this work, phasor measurement units are employed to monitor the power
system and renewable energy systems are used to mitigate the power quality
problems occuring in the grid. A controller must detect, classify and issue a
control signal to the renewable energy system to compensate and/or attenuate
any deviation in the system performance as compared to the healthy situation.
