Placement of shunt VAR compensator based on sensitivity analysis

Abstract

Voltage stability is a common issue in developing power system. It is mainly affected by reactive power balance in the system. If reactive power is not well planned and managed, there is possibility of occurrence of voltage instability in the system. One solution to prevent voltage instability in the system is by VAR compensation. In this work, new technique to determine the placement of different types of shunt VAR compensators based on sensitivity method is presented. Simultaneous planning of SVC and STATCOM placement is also conducted. Improvement in system stability is achieved using the method.
