“…A few publications have investigated the possibility of using variable-speed WPPs actively to damp power system oscillations [17]- [20]. In a recent PhD thesis by Elkington it is concluded that DFIG based WPPs can provide a positive contribution to damping of power system oscillations by adding an auxiliary controller [21].…”

Abstract-Small-signal stability analysis of power system oscillations is a well established field within power system analysis, but not much attention has yet been paid to systems with a high penetration of wind turbines and with large wind power plants. In this paper an analysis is presented which assess the impact of full-load converter interfaced wind turbines on power system small-signal stability. The study is based on a 7 generator network with lightly damped inter-area modes. A detailed wind turbine model with all grid relevant control functions is used in the study.

“…High proportional integration of wind power generators has an important influence on the dynamic stability of power system [10], while, at the same time, they play a certain role in improving power system stability [11][12][13]. Recently, several researches have proposed the possibility of using doubly-fed induction generator (DFIG)-based wind farms to improve damping performance and enhance the dynamic stability of wind power integrated power systems [14][15][16][17][18][19][20][21]. Many novel control schemes have been proposed for DFIGs to enable them to provide an auxiliary power system stabilization function or contribute to system voltage support during network faults [20][21][22][23][24][25].…”

Abstract:The potential of utilizing doubly-fed induction generator (DFIG)-based wind farms to improve power system damping performance and to enhance small signal stability has been proposed by many researchers. However, the simultaneous coordinated tuning of a DFIG power oscillation damper (POD) with other damping controllers is rarely involved. A simultaneous robust coordinated multiple damping controller design strategy for a power system incorporating power system stabilizer (PSS), static var compensator (SVC) POD and DFIG POD is presented in this paper. This coordinated damping control design strategy is addressed as an eigenvalue-based optimization problem to increase the damping ratios of oscillation modes. Both local and inter-area electromechanical oscillation modes are intended in the optimization design process. Wide-area phasor measurement unit (PMU) signals, selected by the joint modal controllability/ observability index, are utilized as SVC and DFIG POD feedback modulation signals to suppress inter-area oscillation modes. The robustness of the proposed coordinated design strategy is achieved by simultaneously considering multiple power flow situations and operating conditions. The recently proposed Grey Wolf optimizer (GWO) algorithm is adopted to efficiently optimize the parameter values of multiple damping controllers. The feasibility and effectiveness of the proposed coordinated design strategy are demonstrated through frequency-domain eigenvalue analysis and nonlinear time-domain simulation studies in two modified benchmark test systems. Moreover, the dynamic response simulation results also validate the robustness of the recommended coordinated multiple damping controllers under various system operating conditions.

“…The results show that DFIG wind turbines equipped with PSS are able to damp low-frequency power system oscillations effectively. However, the controllers used in [7] and [9] are based on rotor flux magnitude and angle control (FMAC) approach which is different from the standard widely used vector control approach in commercial DFIG wind turbines [11].…”

This paper analyses the effect of replacing existing synchronous generators equipped with power system stabilizers (PSS) by DFIG based wind farms on the damping of power system oscillations in a multi-machine power system. A power system stabiliser was designed to enhance the capability of DFIG to damp power systems oscillations. The validity and effectiveness of the proposed controller are demonstrated on the widely used New England 10-machine 39-bus test system that combines conventional synchronous generators and DFIG based wind farms using eigenvalue analysis and nonlinear simulation. The nonlinear simulation is used to demonstrate how the damping contribution of DFIG based wind farms is affected by different operating conditions within the same wind farm and stochastic wind speed behaviour. The results show that installing conventional fixed parameters PSS within reactive power control loop of DFIG rotor side converter has a positive damping contribution for a wide range of operating conditions. Furthermore, the results clearly show that DFIG based wind farms equipped with the proposed farm level PSS can damp power system oscillations more effectively than synchronous generators PSS.
