Voltage stability is an important issue to be studied in power systems. The ever-increasing demand of electrical energy, new power generation plant installations to meet the increasing demand to meet the increasing demand, and failures in the power system adversely affect the voltage stability. Today, Flexible Alternating 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 demand and 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 voltage stability. Static Var Compensator (SVC) and Thyristor Controlled Series Capacitor (TCSC) from FACTS devices, Fuel Cell (YH), Solar Power Plant (GES), and Wind Power Plant (RES) from DGs are connected separately and together in the power systems. Changes in bus voltage values and loading parameters of power systems are analyzed.
