Abstract
In this paper the Static Var Compensator (SVC) is used to improve the voltage of the IEEE 14 Bus power system network. We focus on the voltage level of most majoring issue in IEEE – 14 bus system with constant loads. For doing that we are using NEPLAN software. In this work, firstly we have analyzed IEEE-14 bus system under the standard test data and after that analyzed IEEE-14 bus system with Static-Var-Compensation under the standard test data by changing its location over all buses, then we have compared all the result with the original power flow results of IEEE-14 bus system for choosing the best place of SVC of improving a voltage level of all buses.
