Summary

INTRODUCTION

THE ENERGY industry is undergoing a profound transformation around the world. Decreases in natural resources and increasing demand for electricity are some of the reasons for this change. Many studies have been done to maximize the capacity of existing transmission systems with high reliability and stability. FACTS technology has a critical role in transmission line planning. Because it creates new opportunities to control the power and increase the available capacity [2, 3]. Due to the increase in population and economy, there is a need to increase the flexibility, reliability and capacity of existing transmission systems. Due to changing market conditions, electrical utilities are looking for various ways to operate existing transmission lines at maximum limits. To achieve these goals, FACTS devices are used that can control the power flow and increase the transmission capacity [4]. FACTS devices commonly used in power systems are Static Var Compensator (SVC), Static Synchronous Compensator (STATCOM), Thyristor Controlled Series Compensator (TCSC), Static Synchronous Series Compensator (SSSC) and Unified Power Flow Controller (UPFC) [6]
