With the ongoing load increase in current power systems, voltage stability analysis has become an essential tool to ensure that a power system can withstand different loading variations. In this scenario, this work deals with parameter uncertainties and control selection in voltage stability analysis of power systems. The main contributions of this thesis are related to: • Modelling: – A new static power system model is proposed. The new model enables na unified analysis of different voltage instability mechanisms. Specifically, all static bifurcations are transformed into saddle-node bifurcations. – A new model to take parameter uncertainties into account is proposed, where parametric variations are represented by a Brown...
