This paper deals with multiobjective nonlinear system identification applied when modelling the relation of firing angle and equivalent reactance of a thyristor controlled series capacitor (TCSC). The mathematical representation chosen is NARMAX (Nonlinear AutoRegressive Moving Average with eXogenous inputs) due to its capability in modelling nonlinear

A tracking estimator for the firing angle of the Thyristor Controlled Series Capacitors (TCSC)
Electric Power Systems Research, 2005The firing angle and the fundamental frequency equivalent impedance are the two defining parameters of a Thyristor Controlled Series Capacitor (TCSC). They can be used as the feedback signals in effective control of the TCSC. This paper presents a discrete-time tracking estimator, which is used for dynamically tracking the firing angle. The fundamental

This paper proposes a remedial action scheme (RAS) based on thyristor controlled series capacitors (TCSCs) to cope with false data injection (FDI) cyberattacks leading to tie-line congestions in transmission systems. To develop such a RAS, a three-level framework is designed. The first level of the framework is associated with the planning phase, where

Abstract The increase of nonlinear devices in power systems leads us to consider their adverse effects on the waveform distortion, and consequently, the effects and propagation of this harmonic distortion over the whole power system. This paper presents the analysis of the adverse impact caused by the harmonic distortion generated by the thyristor ...

This paper describes an adaptive method for control of a TCSC device for power oscillation damping. The aim is to mitigate power oscillations in power systems with one dominating oscillation mode. To design the controller, a simple generic model of the power system with only a few variables is used.

The thyristor controlled series capacitor (TCSC) is one of the most effective flexible AC transmission system (FACTS) devices. It offers smooth and flexible control of the line impedance with much faster response compared to the traditional control devices. While numerous studies concerning the utilization of these devices have been carried out so far,

This paper addresses a systematic controller design for the TCSC device in power systems based on a linear matrix inequality (LMI) pole placement technique. Requirements of performance can be expressed in terms of LMI's. In our formulation we combine a H/sub /spl infin// controller design with some regional pole placement constraints using LMTs.
