Unbalance Mitigation via Phase-switching Device and Static Var Compensator in Low-voltage Distribution Network
Bin Liu, Ke Meng, Zhao Yang Dong +2
As rooftop solar PVs installed by residential customers penetrate in low voltage distribution network (LVDN), some issues, e.g. over/under voltage and unbalances, which may undermi…
