Primary Frequency Stability Support of a DFIG in Association With Pitch Angle Control
Frontiers in Energy Research, 2022 For an electric power grid that has large penetration levels of variable renewable energy including wind generation and photovoltaics, the system frequency stability is jeopardized, which is manifest in lowering frequency nadir and settling frequency ...

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 ...

Minimally Supported Frequency (MSF) d-Dilation Wavelets [PDF]
Mathematics, 2021 In this paper, we provide a geometric construction of a symmetric 2n-interval minimally supported frequency (MSF) d-dilation wavelet set with d∈(1,∞) and characterize all symmetric d-dilation wavelet sets. We also provide two special kinds of symmetric d-dilation wavelet sets, one of which has 4m-intervals whereas the other has (4m+2)-intervals, for m ...
