To improve the voltage profile and reduce power losses in industrialization, one of the methods is by compensating for reactive power in the system, namely, installing a Static VAR Compensator (SVC) and setting the SVC reactive power injection value into an 11 kV distribution system to obtain an optimization value determined by simulation using ETAP software, fast decoupled load flow method, and simulation process with a trial-and-error approach. The 38th simulation produces the effect of changes in the value of SVC reactive power injection, namely a voltage drop of 150 Volt on each 11 kV bus, decreasing the reactive power of 3 kVar on Bus101 and 34 kVar on Bus102, reducing active power losses of 0.8 kW on Bus101 and 3.5 kW on Bus102 and reducing reactive power losses of 0.5 kVar on Bus101 and 3.1 kVar on Bus102. The value required for SVC minimum reactive power injection while still achieving improved working voltage profile and reduced power losses in the system is 0 kVar. The error values in this simulation are the phase voltage difference of 119 Volt or 1.07%, the difference in the active power of -1.459 MW or -8.15%, the difference in reactive power of 0.655 MVar 12.29%, and the difference in factor power of -2.8 or -2.92%.
