Nonlinear controller design of thyristor controlled series compensation for damping inter-area power oscillation

TCSC Nonlinear Adaptive Damping Controller Design Based on RBF Neural Network to Enhance Power System Stability

“…In dynamic application of the TCSC, various control techniques have been proposed for damping power oscillations to improve the system dynamic response [10][11][12][13][14][15][16][17][18][19]. Some evolutionary algorithms (EA) have been used optimal tuning of the TCSC based damping controller in order to enhance the damping of the power system low frequency oscillations in Ref.…”

“…To reflect the nonlinearity of the power system and adapt a wide range of operating conditions, some nonlinear control schemes for the TCSC are proposed in Ref. [17][18][19]. These nonlinear controllers are expected to acquire good performance at any operating condition.…”

Adaptive coordinated passivation control for generator excitation and thyristor controlled series compensation system

“…It is installed in long-distance transmission systems for rapid adjustment of the effective value of a capacitor in series with transmission line by making use of the short-time over-load capability of the capacitor (Zhang & Zhou, 1999). It can change line equivalent reactance dynamically to control power flow, damp the power oscillation (Li, 2006), improve system stability (Dimirovski, Jing, Li, & Liu, 2006;Zhu, Liu, Cai, & Ni, 2006) and increase power transfer limit (Chaudhuri & Pal, 2004;Mei, Shen, & Liu, 2003;Zhang, 2002). Yet, serious situations of dynamical power system stability can occur involving bifurcation and chaos prior to power system stabilizes in a steady state due to rather realistic internal and external disturbances.…”

Robust Coordinated Passivation Control for Generator Excitation and TCSC System

“…In the steady state, FACTS devices like TCSC help in controlling voltage stability and increasing the power flow through a line due to its reactive power compensation capacity. However, the other important aspect of these controlling devices is their use during large disturbances such as faults because of their capability to improve the transient stability and damp oscillations in power systems (Dimirovski et al, 2006;Farsangi et al, 2004;Li, 2006). The effectiveness of TCSC based controllers in enhancing the transient stability limit has been studied in (Chaudhuri and Pal, 2004;Mei et al, 2003).…”
