SUMMARY This paper describes two types of rotary loop flow controller, one is series type and the other is unified power flow controller (UPFC) type. Both of them can maintain the suitable voltage level of distribution system even with a large and uneven penetration of distributed generation. The configurations of proposed controllers are essentially same as wound rotor induction machine with no slip rings. The proposed controllers are less costly, more efficient, and more tolerant to overvoltages/currents as compared to power electronics‐type controllers. Further, UPFC‐type rotary loop flow controller has additional advantages like relatively smaller capability and ability to control reactive power than the series type of rotary loop flow controller. The proper functioning of the proposed controllers is confirmed through simulations and experiments.
