“…A decline in damping is occurring in power systems due to the increasing proportion of power electronics in new power systems, and at this time the system can exhibit negative damping for low-frequency oscillations, which can worsen the power system. The use of power system stabilizers (PSS) to increase system damping and thus suppress low-frequency oscillations is a common method in conventional power systems [10][11][12][13]. Reference [14] elucidates the effect of wind power on small disturbance stability and introduces control methods for wind turbines to suppress internal and power system oscillation modes.…”

The grid integration of large-scale wind power will alter the dynamic characteristics of the original system and the power distribution among synchronous machines. Meanwhile, the interaction between wind turbines and synchronous machines will affect the damping oscillation characteristics of the system. The additional damping control of traditional synchronous generators provides an important means for wind turbines to enhance the damping characteristics of the system. To improve the low frequency oscillation characteristics of wind power grid-connected power systems, this paper adds a parallel virtual impedance link to the traditional damping controller and designs a DFIG-PSS-VI controller. In the designed controller, the turbine active power difference is chosen as the input signal based on residual analysis, and the output signal is fed back to the reactive power control loop to obtain the rotor voltage quadrature component. With DigSILENT/PowerFactory, the influence of the controller parameters is analyzed. In addition, based on different tie-line transmission powers, the impact of the controller on the low-frequency oscillation characteristics of the power system is examined through utilizing the characteristic root and time domain simulation analysis.
