mitigation devices

This work tackles in a practical way the problem of short-term voltage stability at bulk power systems from the point of view of the overhead lines parameters: length and compactness. With that aim the 9-bus IEEE test system, properly modified to tailor the needs of the study, is simulated in Simulink under high load conditions for different line parameters, analysing the effects of these parameters on the severity of the instability and the recovery rate of the system under different scenarios: no FACTS, SVC and STATCOM. The main findings of the study are included in the conclusions.
