Abstract

Much attention has been paid to FACTS devices. The STATCOM (static compensator) is a FACTS device used to maintain voltage stability and is usually represented as a time-invariant model. This model can then be used to design an efficient nonlinear control law, based on exact linearization via feedback. In this paper, the control law is optimized in order to stabilize the internal dynamics of the STATCOM. Furthermore, the model is implemented in the EUROSTAG software in order to analyse the influence of the control law on the transient response of the power system
