Improving Voltage Stability of Doubly Fed Induction Generator - based Wind Farm using STATCOM

Abstract

Wind power is one of the most promising renewable resources and Doubly Fed Induction Generator (DFIG) is considered the most cost effective generator for connecting wind power to the grid as it has advantages over other types of wind generators such as operating under variable wind speeds, moderate size of power electronics, and complete control of active and reactive power. But it has consequences on the performance of power system especially power system stability. This paper states the influence of DFIG location on small signal stability using Eigenvalue analysis. Then, Evaluating PV Curve of critical bus as an indicator to state the impact of integrating wind power through DFIG on the voltage stability of power system under different Penetration levels. Besides approving the optimal Mvar for each penetration level to operate the system with wind power in a stable way using trial and error method. The proposed simulation is

STATCOM Controller Tuning to Enhance LVRT Capability of Grid-Connected Wind Power Generating Plants

“…Elzemeity et al in [49] investigate the optimal location of WPPs in the IEEE 39 bus system by sorting the possible locations in ascending order of electromechanical oscillations using Eigenvalue analysis. e best five locations with less electromechanical oscillations are obtained as [50] in which buses 30, 34, 37, and 39 are obtained as the optimal location for WPPs, and Shi et al in [51] who obtain optimal locations as buses 38 and 37.…”
