Voltage sags constitute 80% of power quality problem, and Dynamic Sag Corrector (DySC) has been considered to be an effective custom power device which mitigates voltage sags. DySC has a concise structure compared with dynamic voltage restorer (DVR). DySC adopts different compensation strategies according to the loads’ sensitivity to voltage amplitude and phase jump. This paper proposes a novel compensation strategy named integrated compensation strategy for DySC. The simulation test for single-phase voltage sag compensation verifies that the proposed strategy can mitigate the phase jump accompanied voltage sags and decrease the amplitude of injecting DySC voltage.
