This paper presents an elaborated mathematical analysis of the line loss minimum conditions of loop distribution systems. In order to achieve these conditions, the Unified Power Flow Controller (UPFC), a typical Flexible AC Transmission Systems (FACTS) device that is capable of instantaneous control of transmission and distribution power flow, is used. For minimizing the total line loss of the loop distribution system, the authors propose two control schemes, the Line Inductance Compensation control and the Line Voltage Compensation control. These control schemes can be applied for controlling the UPFC in the loop distribution system according to the line parameters. The effectiveness of the proposed control schemes has been verified experimentally using a laboratory prototype in a 200V, 6kVA system.
