Influence of the Reactive Power Management for Wind Power Plants in the Dynamic Voltage Stability-a case study

Abstract

Nowadays, the large penetration of wind power generation poses new challenges for the dynamic voltage stability analysis of an electric power system. In this paper is studied the influence of the reactive power management for wind power plants in the dynamic voltage stability of an electric power network under a fault condition, considering two different Double Fed Induction Machines (DFIG) models. The automatic voltage regulators of the generating units, the turbine speed governors and the wind turbine were modeled in detail. Different load models were used and the under load tap changers were taken into account too. The simulation results were obtained using the EUROSTAG software package. Finally, some conclusions that provide a better understanding of the dynamic voltage stability in a system with a large amount of wind power generation are pointed out.
