An Enhanced Frequency Response Strategy of a DFIG Based on Over-Speed De-Loaded Curve
Applied Sciences, 2021 The increasing level of wind power penetration is seriously threatening the frequency stability of the power system. In this article, we suggest an enhanced frequency response strategy of a doubly fed induction generator (DFIG) based on over-speed de ...

A Supervisory Frequency Support Control Scheme for Distributed Pv
, 2023 Increasing penetration of Photovoltaic (PV) generation brings an opportunity, and sometimes necessity, for this new resource to provide ancillary services such as frequency support. Recent efforts toward this goal focused mainly on the large-scale PV plants with identical subsystems but cannot handle distributed PV systems with diversities.
