Determination of VAR Compensator Placement for System Stability Improvement on Java Bali Network

Abstract

Abstract Quality of a power system network can be evaluated from its voltage performance. There are several bus/substation of Java Bali networks that frequently operate in unsatisfied voltage level. As an important part of Indonesian electricity system, quality improvement of this network should be sustainably maintained. The occurring problem can be solved by reactive power compensation. Compensation can be done by installing reactive power compensator into the network. To get an optimal improvement level of voltage performance, the installation location of reactive power compensator must be carefully selected. The selection process can be done by consider the operating voltage, bus sensitivity factor, power angle sensitivity factor and geographic location factor on each location in the network. With consideration of these parameters then the optimal location and configuration of the reactive power compensator can be obtained.
