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...
This paper proposes a systematic analysis and design procedure for simultaneously determining the best locations and input signals of flexible AC transmission system (FACTS) devices in order to damp out inter-area oscillations. First, a modified modal power flow oscillation flow method is developed to determine the nature of the energy exchange over the transmission network in the presence of F...
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...

This paper presents an algorithm, for solving the Optimal Power Flow problem with flexible AC transmission systems (FACTS). The type of FACTS devices is used: thyristor-controlled series capacitor (TCSC). A method to determine the optimal location of thyristor controlled series compensators has been suggested. The proposed approaches have been implemented on an adapted IEEE 26 bus system. The s...
Flexible AC Transmission Systems (FACTs) play a vital role in minimizing the power losses and improving voltage profile transmission system. These increase real transfer capacity of However, optimal location sizing FACTs devices determines extent benefits provided by to Non-optimal solution terms may possibly lead under-compensation or over-compensation phenomena. Thus, robust optimization is p...
The introduction of flexible AC transmission system (FACTS) in a power system reduces the losses, reduces the cost of generation, and improves the stability also improves the load capability of the system. In this paper, a non-traditional optimization technique, genetic algorithm is used to optimize the various process parameters involved of FACTS devices in a power system The various parameter...
In this paper, use of Differential Evolution (DE) based and Particle swarm optimization (PSO) based algorithm for the allocation & coordinated operation of multiple FACTS (Flexible AC Transmission System) devices for the improved power transfer capacity and economic operation of an interconnected power system is presented. Both the DE and PSO based approach is applied on IEEE 30-bus system. The...
In some decades, the demand for electrical power has increased but the generation and transmission remained limited due to limited resources and environmental restrictions. The increased demand for electrical power has also increased the complexity in the transmission system. It resulted in the form of the question of stability of power system. Here the stability of power system with possible m...
The Flexible AC Transmission System (FACTS) in a Power System improves stability, reduces the cost of generation, losses and also improves loadability of the system. In order to use FACTS devices in a Power system to maximum extent, optimal location of FACTS devices is an important consideration. This paper presents the optimal location of series FACTS device for eliminating or minimizing the l...
