Modelling of TCSC dynamics for control and analysis of power system stability
A Thyristor Controlled Series Compensator (TCSC) exhibits great nonlinearity and performs in a complex dynamic process. The aim of this paper is to propose a method that can accurately simulate this process when carrying out power system stability analysis, so that the impact of TCSC on power system stability can be more reasonably evaluated. A method that can incorporate the analysis of the electromagnetic transient process of TCSC into the power system stability analysis is described. Simulation studies using different modelling methods of TCSC are presented. The simulation results show the advantages of using the utilisation of the modelling method in power system control and stability analysis.
