Tiivistelmä

This paper analyses the performance of a Q-f droop
based anti-islanding protection (AIP) scheme when the islanded
circuit contains both inverter based DG and directly connected
synchronous generator (SG) based DG. It is found that the
performance of the AIP method is significantly degraded when
SG is present in the island. This is because frequency cannot be
directly manipulated by injecting reactive power when SG is
present. However, feeding reactive power still indirectly affects
frequency and the Q-f droop based AIP scheme thus still
facilitates islanding detection. The simulation results aim to
bring awareness to which extent the presence of SG degrades the
performance of the Q-f droop based AIP.
