The stability analysis given here concentrates on the small signal model and utilises eigenvalue analysis to achieve a result and is illustrated on numerical simulations performed on a 2MW PMSG WECS model.Abstract:
This work studies the stability of a wind turbine with permanent magnet synchronous generator (PMSG) for wind energy conversion systems (WECSs) integrated to power grids using a proposed control strategy. The cascaded control structure uses PI controllers and feedback linearisation which takes the nonlinear relationship between the generator speed and DC-link voltage into account. The stability analysis given here concentrates on the small signal model and utilises eigenvalue analysis to achieve a result. The relation between different modes and state variables is determined by calculating participation factors, based on which effective controller parameters can be selected to improve control performance. Achievable performance is illustrated on numerical simulations performed on a 2MW PMSG WECS model.read more

The impact of large scale wind power generation on power system oscillations
J.G. Slootweg,Wil L. Kling +1 more
TL;DR: In this paper, the effect of wind power on power system oscillations is investigated by gradually replacing the power generated by the synchronous generators in the system by power from either constant or variable speed wind turbines, while observing the movement of the eigenvalues through the complex plane.

Low-voltage ride-through of a full converter wind turbine with permanent magnet generator
J.F. Conroy,R. W. G. Watson +1 more
Abstract: The low-voltage ride-through capability of a 2 MW full converter wind turbine with permanent magnet synchronous generator is investigated herein. A detailed description of the system, its controller options and its behaviour when subjected to a severe voltage dip, is presented. A control scheme for the turbine that allows it to withstand severe voltage dips is designed and simulated. This control scheme emphasises the regulation of the dc-link voltage and minimisation of the drive train torque surplus. Also, the level of modelling detail required for stability analysis is analysed and discussed.
