TL;DR: In this article, the frequency response capability of the full converter variable speed wind turbine generator (FCWTG) with permanent magnet synchronous generator (PMSG) is investigated and a control scheme is developed that improves the frequency control performance.

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.

TL;DR: In this paper, the aggregate modelling options for a wind farm with 5 MW full-converter WTGs (FCWTGs) using permanent magnet synchronous machines are presented, where a braking resistor in the DC circuit of the converter system is employed as a means of satisfying the latest grid code requirements.

TL;DR: This paper critically reviews the existing FRT standards (grid‐code requirements) and FRT strategies implemented/ proposed for major DRERs, such as wind energy conversion systems (WECSs), solar photovoltaic (PV) systems, and microgrids, and suggests an augmented approach to achieve a sustainable renewable energy future.

TL;DR: In this paper, the torsional damping requirements for megawatt scale wind turbines having synchronous generators with full-wave ac/dc/ac inversion technology were examined.
