Utilization of DFIG‐based wind model for robust damping of the low frequency oscillations in a single SG connected to an infinite bus

Summary In this study, a single synchronous generator connected to an infinite bus (SMIB), augmented by a DFIG, was assessed by studying a system model at various operating positions, wind speeds, and DFIG ratings. In addition, several tests were conducted to compare power systems with and without a connected DFIG. Following detailed analysis and residual configuring, we identified the optimal positioning of the DFIG rotor‐ and grid‐side converter controllers for mitigating small oscillations. Three distinct signals were tested at the selected position to determine the most robust signal in terms of several key characteristics, namely, high average residue magnitude and average phase angle of residue. This was done to ensure system stability without reducing or destabilizing other system modes under a range of operating conditions. Based on the results of eigenvalue analysis, participation factor calibration, and time domain simulation, this study validated and demonstrated the effectiveness of the proposed modified system.
