Improvement to observability measures of LFO modes in power systems with DFIGs

Shenghu LI

Frontiers in Energy 2021, Volume 15, Issue 2, Pages 539-549 doi: 10.1007/s11708-019-0617-z

Abstract: Observation of the low-frequency oscillation (LFO) modes in power systems is important to design theequations of the power system with the doubly-fed induction generators (DFIGs) are derived to find the LFOThe numerical results from the small and large-disturbance validate the LFO modes caused by the DFIGsparameters is chosen based on the sensitivity model to improve the observability and damping ratio of the LFO

The nonlinear singularity phenomenon of low frequency oscillation in power system

Ma Jinglan,Wang Wei,Wan Jingsheng,Zhang Yongli

Strategic Study of CAE 2009, Volume 11, Issue 8, Pages 93-96

Abstract:

LFO (Low Frequency Oscillation) is a main aspect that affects power systemIn this paper, the inherent reason that causes LFO is discussed.With Hopf bifurcation theory, it is analyzed
