Abstract

Today, there is a large increase in the demand for electricity. The transmission and distribution networks, however, cannot fulfill unbound demands due to the scarcity of resources. Power lines have losses which make the situation more unfavorable for maximum power transfer. Implementing a flexible AC transmission system (FACTS) is one of the best ways to reduce line losses. This paper proposes a FACTS-based method for minimizing the fault current in the system. Switchgear and protection equipment also perform better when this is done. Moreover, due to the reduced fault current of the switched system, a larger amount of power can be transmitted. Static synchronous series compensator (SSSC), static synchronous compensator (STATCOM), and unified power flow controller (UPFC) are evaluated in this case. With STATCOM and UPFC, fault currents are significantly reduced. Furthermore, STATCOM and UPFC can also reduce the fault currents in the power system in addition to voltage regulation and power flow control. A MATLAB/Simulink model is used to evaluate the model’s feasibility.

Highlights

Humanity has been blessed with the greatest gift of all with electricity
IEEE 9-BUS 3 machine system [24] is used as the basis for this system analysis. e system is connected to a number of flexible AC transmission system (FACTS) devices for further analysis
By deploying the FACTS devices in appropriate locations, the power system will be more secure since the bus voltage, power flow, and short circuit current will be controlled to the desired level [17]

Summary

Introduction

Humanity has been blessed with the greatest gift of all with electricity. Modern life would not be possible without electricity. Ese FACTS devices can be used to reduce the fault current in the system [18, 19]. Researchers have considered the first-generation FACTS devices [18] and reduced the voltage level for fault current reduction [19]. Auxiliary equipment such as power electronic equipment-based fault current limiter (FCL) [20, 21] and superconducting fault current limiter (SFCL) [22, 23] have been used. Without using an extra current limiter the second-generation FACTS devices can be used as fault current limiters keeping the voltage level constant.
