The subsynchronous interaction between the wind farm's grid-side converter and the seriescompensated transmission line can trigger subsynchronous oscillations (SSO). The wind power system oscillation frequency depends on the actual operational conditions. This paper proposes a repetitive-PI control strategy to mitigate oscillations under various conditions. The repetitive-PI control offers fast dynamic performance and high steady-state accuracy, which can eliminate steady-state errors and improve the system's robustness. Firstly, the repetitive-PI composite controller is derived based on the frequency domain expansion of the repetition controller. Then, the stability of the repetitive-PI composite controller is analyzed, and its main parameters of it are designed. Finally, to demonstrate the efficacy of the proposed suppression technique for SSO, simulations are conducted under different wind speeds, series compensation levels, and numbers of operating wind turbines. The time-domain simulation results and impedance modelbased analysis demonstrate that the proposed repetitive-PI control strategy enhances the system's damping performance and improves its disturbance resistance.INDEX TERMS Subsynchronous oscillation, wind power system, series-compensated transmission line, repetitive-PI control.

“…One notable approach in this field is the development of a closed-loop ADRC scheme, which effectively addresses complex control problems encountered in various applications. It has been successfully implemented in the induction generator AC power system [14], vehicle dual-motor steer-by-wire system [16], modular multilevel converters [17], ship heading [18], and doubly-fed induction generator [19] etc. Document [20] introduces an enhanced linear active disturbance rejection controller (ELADRC) with the cascaded LESO to deliver a relatively prompt and precise estimation of the overall disturbance.…”

In this study, a novel active disturbance rejection controller (ADRC) is proposed to significantly improve the speed control performance of permanent magnet synchronous motor (PMSM). The conventional ADRC, namely linear active disturbance rejection controller (LADRC) and nonlinear active disturbance rejection controller (NLADRC), both them have their own merits and drawbacks. Thus, an enhanced switching active disturbance rejection controller (ESADRC) is developed to counteract the impacts of the speed-loop for the PMSM. The proposed ESADRC comprises several novel components including a novel tracking differentiator (TD), a novel switching extended state observer (SESO), a novel switching state error feedback (SSEF), and a cascaded extended state observer (ESO). The cascaded ESO is responsible for estimating the remaining disturbance after the SESO. Through comparative verification, it is verified that the proposed ESADRC outperforms the traditional ADRCs in terms of performance.

Advanced control and mitigation solutions are required due to the enormous challenges posed by sub‐synchronous control interaction in wind farms. These concerns include system instability, potential damage to turbines, and grid stability issues. This research presents the probabilistic robust damping controller, an adaptive control approach, to address the issues in grid‐connected wind farms. The innovation employs the balanced remora optimization algorithm to optimize controller parameters, ensuring system stability under various conditions. For permanent magnet synchronous generator‐based wind farms with weak grid circumstances, critical elements such as the DC‐link voltage, the d‐q axis current reference, and the actual values in the grid‐side converter are essential for problem mitigation. The controller generates controlled output using these input signals. The MATLAB‐based implementation demonstrates the controller effectiveness in damping issues within a series‐compensated doubly fed induction generator. Comparative analysis with conventional controllers under different grid conditions and disturbances validates its superior performance. Time‐domain simulations, both with and without time delay, further confirm the controller's ability to enhance system stability and dampen the issues. Four schemes are used to evaluate the doubly fed induction generator‐based wind farms: wind speed at 13 m/s with 75% series compensation, 7 m/s with 75% compensation, 9 m/s with 45% compensation, and 9 m/s with 60% compensation. Under short circuit ratio, the wind farms based on permanent magnet synchronous generators are analyzed in three scenarios: normal, strong, and weak cases.
