“…However, the transfer functions can merely predict the input-output dynamics at the converter terminal, i.e., how a single converter interacts with the rest of the system. The effects of state variables on the stability margin of the system are not identified, and consequently the system oscillation modes with different damping levels cannot be observed in the frequency domain [74].…”

The large-scale integration of power electronicbased systems poses new challenges to the stability and power quality of modern power grids. The wide timescale and frequency-coupling dynamics of electronic power converters tend to bring in harmonic instability in the form of resonances or abnormal harmonics in a wide frequency range. This paper provides a systematic analysis of harmonic stability in the future power-electronic-based power systems. The basic concept and phenomena of harmonic stability are elaborated first. It is pointed out that the harmonic stability is a breed of small-signal stability problems, featuring the waveform distortions at the frequencies above and below the fundamental frequency of the system. The linearized models of converters and system analysis methods are then discussed. It reveals that the linearized models of ac-dc converters can be generalized to the harmonic transfer function, which is mathematically derived from linear time-periodic system theory. Lastly, future challenges on the system modeling and analysis of harmonic stability in large-scale power electronic based power grids are summarized.

“…This significant penetration of embedded generations of various plants means developing new techniques for output power smoothing, flicker analysis, mechanical stress on turbines and transient stability improvement of associated generators for secure grid connection of the energy conversion systems [1][2][3][4]. Henceforth, many papers have been proposed for analysis and prediction of torsional oscillations of the drive train of steam, hydro and wind turbines [5][6][7][8][9][10]. In Refs.…”

This paper focuses on the state space modeling approach and output torques prediction of torsional vibrations for variable speed wind turbines. The multi-body system model under study is mainly comprised of a wind turbine, a three stage planetary gear box and an induction generator. The masses-springs approach of shaft system differential equations is developed from Newton's law and Lagrange formulas. For an easy comprehension for electrical engineers and tutorial purpose, an electrical equivalent circuit of the system is proposed by using mechanical and electrical components similarities. Extensive numerical simulations are performed to investigate system mechanical resonances and impacts of damping factors on the system dynamic and stability.
