“…Integration can be implemented directly (passively controlled) [11,[15][16][17] or indirectly through a converter (actively controlled) [9,11]. In the process of direct integration, the generator controller views the storage as a supplementary component and adjusts accordingly.…”

“…It is worth mentioning that the recovery mechanism of the discharged energy from the SCs without triggering a secondary frequency drop is not mentioned in this study. In [15], the authors suggest a control approach for WTs utilising SCs to manage voltage and frequency regulation. This strategy aims to address voltage ride-through and frequency regulation during power grid faults.…”

This study aims to hybridise a type 4 wind turbine, a supercapacitor, and a battery storage system at the asset level. This hybridisation is based on the experimental hybridised wind turbine currently being commissioned at the Technical University of Denmark, which highlights the practicality and applicability of the proposed hybrid configuration. This hybrid configuration effectively leveraged the strengths of each storage system while mitigating its drawbacks, creating a synergistic storage solution to ensure robust simultaneous delivery of frequency services such as FFR and FCR with high ramping requirements. The paramount objective of this study is to guarantee the provision of rapid primary frequency services without necessitating power reservation, and avoiding an escalation in operational stress on both the battery and the wind turbine. The results of this research will pave the way for future investigations into DC-coupled HPP configurations consisting of several hybridised units rather than AC-coupling HPPs.
