A critical factor effecting power transmission systems today is power flow control. The increment of load variation in a power transmission system can lead to potential failure on the entire system as the system has to work under a stressed condition. Thus, the Flexible AC Transmission System (FACTS) are integrated in power system to control the power flow in specific lines and improve the secu...

An Unified Power Flow Controller (UPFC) is a typical Flexible AC Transmission System (FACTS) device playing a vital role as a stability aid for large transient disturbances in an interconnected power system.This paper deals with the design of Feedback Linearising Controller (FBLC) for UPFC.The disturbances are created in the SMIB system and the results are simulated.The results proved the supre...

The Flexible AC Transmission Systems (FACTS) are the static power electronic devices that installed and used in transmission networks to enhance capability of transferring for providing controllability stability. However, optimization site size these is a crucial task due their high capital cost practical capabilities. In this paper, optimal reactive dispatch (ORPD) embedded with two effective ...

This paper presents a comparative study of the performance of distance relays for transmission line high voltage (HV) 400 kV in Eastern Algerian transmission networks at Group Sonelgaz compensated by two different series Flexible AC Transmission System (FACTS) i.e. GTO Controlled Series Capacitor (GCSC) and Thyristor Controlled Series Capacitor (TCSC) connected at midpoint of an electrical tran...

Microgrids (MGs) have emerged throughout the world as major means of integrating a variety distributed energy resource (DER) technologies into distribution system. These DER are mostly coupled through electronic power converters (EPCs). This fact has created new operation challenges these converter-interfaced DERs could compromise MG stability, reliability, and resilience margins. On other hand...

The electric power grid has evolved significantly over the past two decades in response to climate change. Increased levels of renewable energy generation, as a prominent feature this evolution, have led new congestion patterns transmission network. system is originally designed for conventional sources, with predictable flow patterns. Insufficient transfer capability congested systems results ...

Large number of contracted power exchanges among sellers and purchasers, in a deregulated market causes transmission line congestion. Congestion lines undermines the security economy networks. Flexible AC system (FACTS) devices are introduced at appropriate spots to change flow order keep within their capability. In this work, most commonly used unified controller (UPFC) is proposed for achieve...

This paper presents the application of Genetic Algorithm (GA) to assess and enhance Total Transfer Capability (TTC) using Flexible AC Transmission System (FACTS) devices during power system planning and operation. Conventionally TTC is assessed using Repeated Power Flow (RPF) or Continuation Power Flow (CPF) or Optimal Power Flow (OPF) based methods which normally uses Newton Raphson (NR) metho...
