Abstract
Voltage stability is an important issue to be studied in power systems. The ever-increasing demand ofelectrical energy, new power generation plant installations to meet the increasing demand to meet theincreasing demand, and failures in the power system adversely affect the voltage stability. Today, FlexibleAlternating Current Transmission Systems (FACTS devices) are used in power systems to improve voltage stability, and Distributed Generation sources (DGs) are integrated into power systems to meet energy demandand improve voltage stability. In this study, the IEEE 30 bus power system and the North-west Anatolia (KBA) power system are investigated in base (nominal), overload, and line outage cases regarding voltagestability. Static Var Compensator (SVC) and Thyristor Controlled Series Capacitor (TCSC) from FACTSdevices, Fuel Cell (YH), Solar Power Plant (GES), and Wind Power Plant (RES) from DGs are connectedseparately and together in the power systems. Changes in bus voltage values and loading parameters of powersystems are analyzed.
