Metodología para la evaluación y mejora de la estabilidad de voltaje de un sistema eléctrico de potencia

Abstract

In this document the development of a methodology for the improvement of the voltage stability margin (VSM) of a power system is presented, when a contingency (N-1) arises. The control actions used to improve VSM are, the reactive compensation, variation in setpoint voltage of generators, active power redispatch and load shedding. The methodology is developed in MATLAB, and some MATPOWER scripts are used. Additionally, the simulation of contingencies, improvements of VSM is carried out for standard IEEE 9, 39 bus system, and IEEE 300 bus system. Finally, among the results that are in view are: the voltage profiles, PV curves, and generation costs associated with the system by the control actions carried out to improve VSM.
