“…The use of the converters' control capabilities has been recently proposed for damping power swings as well as inter-area oscillations [6][7][8][9] for wind energy systems based on doubly fed induction generators (DFIGs) with back-to-back power electronic converters. A preliminary study exploring the capability of the grid-side converter (GSC) of a DFIG in mitigating SSR is presented in [10,11].…”

Abstract:The increasing presence of wind power in power systems will likely drive the integration of large wind farms with electrical networks that are series-compensated to sustain large power flows. This may potentially lead to subsynchronous resonance (SSR) issues. In this paper, a supplementary controller on the grid-side converter (GSC) control loop is designed to mitigate SSR for wind power systems based on doubly fed induction generators (DFIGs) with back-to-back converters. Different supplementary controller feedback signals and modulated-voltage injecting points are proposed and compared based on modal analysis and verified through root locus analysis to identify the optimal feedback signal and the most effective control location for SSR damping. The validity and effectiveness of the proposed supplemental control are demonstrated on the IEEE first benchmark model for computer simulations of SSR by means of time domain simulation analysis using Matlab/Simulink.

“…Several exploitation concepts and technologies have been deployed all around the world and continuous improvements in wind capture techniques have been introduced to render this type of energy widespread and cost effective [1]. The increased grid penetration of wind energy however, comes with a series of important stability and power quality concerns yet to be taken care of [2], [3], [4].…”

“…In [6] authors concluded that the network resonant modes involved in the SSR phenomena change their frequency and damping ratio as series compensation level and machine speed vary. In [4], the machine's control dynamics were included in the modeling of a DFIG-base WECS 1 connected to the grid through a series compensated line. This modeling allowed authors to assess the impact of control parameters variation in the stability of the system.…”

“…This modeling allowed authors to assess the impact of control parameters variation in the stability of the system. Both [4] and [6] presented a small signal analysis of the system based on the modal and participation factor analyses introduced in [7] and [8] for DFIG-based WECS. All the above mentioned literature has considered a Single Machine Infinite Bus (SMIB) system consisting of only one machine representing a wind-farm as a coherent set of generators, Fig.1.…”

This work studies the Sub-Synchronous Resonance (SSR) interactions that can take place when a DFIG-based wind farm is connected to the electrical grid through a series-compensated transmission line. As opposed to recent literature on the subject, a multiple machine model is employed to represent the wind farm. This representation allows taking into account machine speed variability due to wind parks being spread over large extensions of land. Additionally, a three-mass model is used to describe the dynamics of the turbine-generator set (instead of the recurrently employed two-mass model). The obtained simulation results show that simplified modeling of DFIG-based wind farms can have a fairly significant impact on SSR related studies.
