“…The simulation test platform is based on the MATLAB/Simulink environment and the packaged modules in SimPowerSysterms are used in this simulation test platform, including the wind turbine, PMSG, and VSCs. Meanwhile, the two mass block spring damping model mentioned in [21][22][23][24][25][26][27][28][29][30][31] is adopted to describe the dynamics of flexible drive chain. Therefore, the simulation test platform is relatively close to the actual physical system, due to the adoption of many packaged modules.…”

Because the PMSG (permanent magnet synchronous generator)-based WECS (wind energy conversion system) has some uncertainties, the conventional control strategy with poor robustness is sometimes difficult to meet the performance requirements of control. In order to ensure efficient and stability of the system, this paper proposed a novel PI (proportional-integral)-type SMC (sliding mode control) strategy for PMSG-based WECS uncertainties and presented the detailed analysis and design process. Compared with the conventional control method, the PI-type SMC proposed in this paper not only can make the closed-loop system globally stable, but also has a better robustness and slightly reduced the current ripple and distortion. Finally, the simulation results verify the correctness and effectiveness of this algorithm.

“…4 Meanwhile, for environmental reasons, large-scale wind power is integrated to the grid. 7 So, the investigation on low frequency and shaft oscillations of AC/DC power system with integrated wind farm is necessary. Not only the risk of low frequency oscillation will be increased, 6 but also the shaft oscillation of DFIG will have an impact on the stability of the system.…”

“…All the investigations on low frequency and shaft oscillations in references [1][2][3][4][5][6][7][8][9][10][11][12] are at the pertinence of a certain operating point and is such that the research results may not be applicable when system operating point varies. Multioperating points take into consideration the stochastic variations of the wind power output, the traditional generator output, and the load.…”

This paper focuses on mitigating low frequency and shaft oscillations of AC/DC hybrid power system with integrated wind farm under multi‐operating points. A probabilistic method based on Gram‐Charlier expansion with a hybrid algorithm using moments and cumulates is applied to cope with the issue of oscillations over a wide range of operating points. For low frequency oscillation modes, the damping contribution of DC modulation (DCM) controller and power system stabilizer (PSS) is compared. As for the shaft oscillation mode, the principle analysis and damping contribution of shaft stabilizer are investigated. The damping contribution to modes of low frequency and shaft oscillation of damping controllers is investigated on a five‐machine two‐area AC/DC power system. The major contributions of this paper are (a) investigation of the shaft oscillation, including principle analysis and its suppression measure and (b) application of the probabilistic method to enhance the controllers' capability of adapting to the AC/DC hybrid system over a wide range of operating points.

“…Mandic et al 11 proposed a torsional vibration damper based on the band-pass filters with the generator speed feedback. Fateh et al 12 proposed a new nonlinear control scheme based on the sliding mode control theory to damp drivetrain torsional vibrations, while the control scheme is complex for the DFIG control system. Furthermore, as a widely used control scheme to reduce the power oscillation of synchronous generator, the power system stabilizer (PSS) is introduced in DFIG to suppress the shafting oscillation.…”

Summary The shafting oscillation occurs in the grid‐connected doubly fed induction generator (DFIG)‐based wind power generation system may lead to the low‐frequency oscillation in the grid, which can weaken the dynamic stability of the power system. Thus, this paper focus on the shafting oscillation damping control of the DFIG‐based system. The characteristics of the DFIG shafting oscillation is analyzed. In addition, the four control strategies based on the complex torque coefficient method for improving the shafting oscillation damping of the grid‐connected DFIG are investigated. Furthermore, a typical 2‐MW DFIG wind power generation system is used for case study under various wind speed on DIgSILENT/PowerFactory. The simulation results validate the effectiveness of the four control strategies. Finally, the detailed comparative analysis and suggestion is presented. The research results of this paper can help to develop an optimal control strategy to suppress the shafting oscillation in the DFIG system under different conditions.
