Thyristor-controlled series capacitor (TCSC) as one of the most important FACT devices can be used for various purposes such as reactive power compensation, voltage control, dynamic stability improvement and power oscillation damping in power systems. Practical aspects on sizing of TCSC elements must be considered to have the fast and reliable switching from capacitor to inductive region and vi...

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...

Loss minimization in power system is an important research issue. Transmission line losses in a power system can be minimized by means of reactive power compensation. The continuous demand in electric power system network has caused it to be heavily loaded leading to voltage instability. This phenomenon has also led to voltage profile depreciation below the acceptable secure limit. The signific...

This paper presents the use of Self Adaptive Firefly Algorithm to identify the optimal placement of Thyristor Controlled Series Compensator (TCSC) in a power system network. The objective is to minimise the transmission loss in power system network with the placement of TCSC. To validate the proposed algorithm, simulations are performed on three IEEE test system using MATLAB software package. S...

The blockchain-based smart contract lacks privacy, since the state and instruction code are exposed to public. Combining smart-contract execution with Trusted Execution Environments provides an efficient solution, called TEE-assisted contracts (TCSC), for protecting confidentiality of states. However, combination approaches varied, a systematic study is absent. Newly released systems may fail d...

This paper focuses on multi-objective designing of multi-machine Thyristor Controlled Series Compensator (TCSC) using Strength Pareto Evolutionary Algorithm (SPEA). The TCSC parameters designing problem is converted to an optimization problem with the multi-objective function including the desired damping factor and the desired damping ratio of the power system modes, which is solved by a SPEA ...

In this paper a novel method for finding the fault zone on a Thyristor Controlled Series Capacitor (TCSC) incorporated transmission line is presented. The method makes use of the Support Vector Machine (SVM), used in the classification mode to distinguish between the zones, before or after the TCSC. The use of Discrete Wavelet Transform is made to prepare the features which would be given as th...

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.
