A loop distribution system is mostly preferred in the distribution network rather than the radial one for reliable power and satisfaction of the customers with comparably less power loss. This paper proposes a method to achieve line loss minimization by installing a “Sen” Transformer (ST) in a loop distribution system. An ST works as a series voltage regulator or impedance regulator in the loop distribution system to address power quality issues with better economic impact by inserting the compensating voltage or virtual impedance in the line. In the present work, the use of an ST is proposed in the loop distribution system with two different control schemes for balanced power flow with a reduction in line loss. The total minimization in line loss can be obtained if the summation of the all voltage drop across the line inductor in the loop distribution system tends to be zero. The total reduction in line loss can be realized by installing the ST in the line that eliminates the circulating current by injecting the compensating voltage. Validation of the present work has been done by the simulating loop distribution system with an ST and the loop current is eliminated to address the line loss minimization problem with two different control schemes, line voltage compensation scheme (LVCS) and line inductance compensation scheme (LICS).
