Congestion Management (CM) is a very important aspect of present deregulatory power environment. In the restructured power market congestion occurs when the transmission network is unable to accommodate all the desired transaction due to violation of system operating limit. Increase of real power loss, increase of load demand compared to generated power, lack of Var sources or the fall of volta...

This paper presents an approach to find the optimal location of thyristor-controlled series compensators (TCSC) in a power system to improve the loadability of its lines and minimize its total loss. Also the proposed approach aims to find the optimal number of devices and their optimal ratings by using genetic algorithm (GA) with taking into consideration the thermal and voltage limits. Examina...

This paper focuses on the optimal power flow solution and the enhancement of the performance of a power system network. The paper presents a secured optimal power flow solution by integrating Thyristor controlled series compensator (TCSC) with the optimization model developed under overload condition. The Teaching Learning Based Optimization (TLBO) has been implemented here. Recently, the oppos...

The paper reviews modeling of thyristor–controlled series capacitors (TCSC) which are highly nonlinear systems with continuous and discontinuous states, and proposes three nonlinear controllers for it: (1) An approximate feedback linearization control (FLC) (2) A sliding surface–like design (3) Control in transformed coordinates. Detailed (switched) time– domain simulations are used to verify t...

<span>From a transmission system point of view, any overload on the grid lines during operation in situations such as peak load or emergency conditions include line outage generator outage, is refers to congestion. Generally, congestion can be managed by controlling power flow. On other hand, series compensation has significant role control flow; therefore, equipment like fixed capacitor ...

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...

With the introduction of competition in the existing electrical market, it becomes necessary to enhance the transmission capacity of the power system through the existing transmission lines. The utilization of FACTS technologies can have significant impact on power system reliability. Low cost and feasibly better improvement can be achieved by using power electronics based devices in the system...

A new approach for protection of transmission line including TCSC is presented in this paper. The proposed method includes application of Fuzzy Neural Network for distance relaying of a transmission line operating with a thyristor controlled series capacitor (TCSC) protected by MOVs. Here the fuzzy neural network (FNN) is used for calculating fault location on the TCSC line. The FNN structure i...

Effectiveness of an electrical distribution system depends on the stability its voltage profile. Several methods such as Static Compensator (SC), Thyristor Controlled Series Compensation (TCSC) and Capacitor have been applied for system. However, these characterized by harmonic variation low efficiency. Therefore, this research paper Shunt Switching (SSC) 11 kV located at Monatan, Ibadan, Oyo S...
