This paper describes a new relaying algorithm for the protection of transmission lines with a Thyristor Controlled Series Compensator (TCSC). The algorithm is based on the pattern of traveling waves generated during a fault event. Several tools like modal analysis, the discrete wavelet transform and a probabilistic neural network trained to work with the energy contained in the wavelet transfor...

In a deregulated power systems environment, congestion management is one of the technical problem needs to maintain a system as stable condition. One of the objective functions in congestion management is N-1 contingency analysis. Using N-1 contingency analysis find out the worst line outage and analysis that line, maintain the whole system as stable after the line outage. Two types of Methodol...

in today’s restructured environment, congestion management plays an essential role in power system operation. different methods are presented and discussed in this respect for congestion management in short-term and long-term intervals. it is attempted in the present paper to investigate the impact mechanism of facts devices and demand response programs together with generation re-dispatch as s...

The usage of renewable energy sources in the power sector has increased day by to preserve non-renewable resources from extinction. growth earnings electricity market also become a critical part as generated integrated system is fluctuating nature. For renewable-associated system, abundant during low-demand hours. These excess units are available due presence like solar, wind, etc. So, better w...

In this investigation, a novel approach is presented to nd the optimum locations and capacity of Flexible AC Transmission Systems (FACTS) devices in a power system using a fuzzy multi-objective function. Maximising the fuzzy satisfaction allows the optimization algorithm to simultaneously consider the multiple objectives of the network to obtain active power loss reduction; i.e., new FACTS devi...

This paper investigates the enhancement of power system stability via coordinated design of Power System Stabilizers (PSSs), Thyristor Controlled Series Capacitor (TCSC)-based stabilizer, and Static Var Compensator (SVC)-based stabilizer in a multi-machine power system. The design problem of the proposed stabilizers is formulated as an optimization problem. Using the developed linearized power ...

Congestion management is one of the technical challenges in a Deregulated power system environment. Two types of Methodologies used in congestion Management are non-cost free methods and cost free methods. In this research work congestion is relieved by using cost-free methods considering FACTS Devices such as TCSC(Thyristor controlled series Compensator) and UPFC (Unified Power Flow Controller...

This paper presents the study of impact harmonic distortion generated by thyristors controlled series capacitor (TCSC) in Algerian electric power system. By applying Fourier transform terminal voltage and switching function, TCSC model is used as a admittance matrix, frequency domain, then integrated into balanced load flow algorithm based on Newton-Raphson method. The has been carried out with...
