Abstract

The problem of voltage instability in Low-Voltage (LV) radial distribution networks is longstanding, mostly because of the insufficiency of the reactive power compensation, rising load demand, and the growth of nonlinear loads. FACTS devices, especially the Static Var Compensator (SVC) and Distribution Static Compensator (D-STATCOM), offer fast and efficient solutions to voltage deviation and power-quality issues. This paper discusses how SVC and D-STATCOM affect the voltage profile of a typical LV radial distribution feeder on the basis of MATLAB/Simulink modeling. The uncompensated system simulation results show that the system is uncompensated and it is operating at 0.889 p.u, which is lower than the acceptable limit. Addition of SVC boosts the voltage to 0.925 p.u., and addition of D-STATCOM boosts the voltage to 0.921 p.u. The Total Harmonic Distortion (THD) of D-STATCOM is much lower than that of SVC (0.80% better than 4.52%). The results show that both devices increase voltage stability, but D-STATCOM has a better power-quality performance, and thus is better adapted to the contemporary LV distribution systems.
