Loss reduction of distribution system using APLC

In this paper the main purpose of the series power converter of APLC is to control power flow in order to reduce losses of distribution system. The aim of shunt inverter is to compensate the reactive power and current harmonics caused by nonlinear load. The suggested APLC not only performs the functions of UPQC but also can effectively reduce power losses in parallel paths. Simulation results, carried out by PSCAD/EMTDC, show that the proposed strategy and configuration can effectively reduce power losses and eliminate harmonic currents for sensitive nonlinear loads.
