A Design of the Series Compensator for the Distribution Network Integrated with Distributed Energy Resource

A novel power quality improvement scheme based on distributed energy resource (DER) and series compensator (SC) is proposed in this paper. The proposed DER-SC scheme can help the sensitive loads ride through the upstream voltage sags by regulating power flow in the distribution network flexibly. An analytical relationship between voltage sag magnitude, phase angle jump and the capacity of the SC is established. Simulation results verify the efficacy of the proposed scheme.
