TLDR
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:
With an increased number of wind turbine generators (WTGs) connected to an electricity network the system operator may request that they participate in frequency control in the event of a sudden unbalancing of power generated and consumed on the system. In this paper the frequency response capability of the full converter variable speed wind turbine generator (FCWTG) with permanent magnet synchronous generator (PMSG) is investigated. A control scheme is developed that improves the frequency control performance, illustrating the importance of the initial active power output of the FCWTG. A method of carefully ending the frequency support of a wind farm is proposed and simulated. The resulting frequency control performance compares favorably to that of a conventional synchronous generator plant.read more

Participation of wind power plants in system frequency control: Review of grid code requirements and control methods
Francisco Díaz-González,Melanie Hau,Andreas Sumper,Andreas Sumper,Oriol Gomis-Bellmunt,Oriol Gomis-Bellmunt +5 more
TL;DR: In this paper, a review of the requirements set by Grid Codes, but also on control methods of wind turbines for their participation in primary frequency control and synthetic inertia is presented. But the authors do not consider the effect of non-synchronized renewable-based power plants (e.g., wind and solar).
