This paper develops an optimization procedure for tuning of power systems stabilizer (PSS) and Thyristor controlled Series capacitor (TCSC) based the power oscillation damping controller (POD)n to enhance Power System stability. Bacterial foraging algorithm (BFA) tries to minimize an Eigen value based multi objective function in which some loading conditions are considered concurrently to ensur...

With the massive increase in the population and, as a result of the expansion of the power grid, new problems such as loss power in network retaliation were created. So studies on this issue began. These studies led to the emergence of FACTs devices. The Flexible AC transmission System (FACTS) devices, such as, thyristor controlled series compensators (TCSC) may be used to enhance system perfor...

Because of its undoubted advantages, the Thyristor Controlled Series Capacitor (TCSC) is one most widely used power-electronic controllers in power systems. However, TCSC has also been a cause concern protective relaying because impact on impedance seen by conventional distance relays, which may lead to an incorrect assessment fault and, consequently, erroneous relay tripping. To overcome these...

This paper presents a new metaheuristic algorithm called BAT search Algorithm (BAT). The BAT search algorithm is used to solve Optimal Power Flow (OPF) problem with the Thyristor Controlled Series Capacitor (TCSC). The TCSC is used to reduce the transmission line losses and improve the voltage profile of the power system. The effectiveness of the BAT Algorithm has been tested for various bus sy...

With the ever increasing complexities in power systems across the globe and the growing need to provide stable, secure, controlled, economic and high quality power especially in the deregulated power market. It is envisaged that FACTS controllers will play a vital role in power systems. This paper investigates the improvement of transient stability of a test system under three phase fault using...

This paper describes a new stochastic heuristic algorithm in engineering problem optimization especially in power system applications. An improved particle swarm optimization (PSO), called Adaptive particle swarm optimization (APSO), mixed with simulated annealing (SA) that will be named APSO-SA is introduced. This algorithm uses a novel PSO algorithm (APSO) to increase convergence rate and inc...

Saluran transmisi yang berfungsi menyalurkan energi dari pusat pembangkit ke beban harus secara efisien. Akan tetapi, jaringan luas memungkinkan pengoperasian saluran menjadi tidak Hal ini terjadinya rugi-rugi daya dan drop tegangan pada sistem. Oleh karena itu, dibutuhkan upaya untuk memanfaatkan kapasitas sistem tersedia efektif, salah satunya dengan memasang perangkat baru seperti TCSC (Thyr...

To meet with the ever-enhancing load demands, new transmission lines should be bolted-on in the existing power system but the economic and environmental concerns are major constraints to this addition. Hence utilities have to rely on the existent power system infrastructure with some modifications. To enhance controllability and boost power transfer potential of the existing power system the us...

Power system security enhancement is a major concern in the operation of power system. In this paper, the task of security enhancement is formulated as a multi-objective optimization problem with minimization of fuel cost and minimization of FACTS device investment cost as objectives. Generator active power, generator bus voltage magnitude and the reactance of Thyristor Controlled Series Capaci...
