Fault ride-through of renewable energy conversion systems during voltage recovery

open access: yesJournal of Modern Power Systems and Clean Energy, 2016
Asymmetrical voltage swells during recovery of a short-circuit fault lead to fluctuations in the dc-link voltage of a renewable energy conversion system (RECS), and may induce reversed power flow and even trip the RECS. This paper studies characteristics

Voltage fluctuations generated by stochastic noise. [PDF]

open access: yes, 2014
(A) Voltage time traces of the model neurons with gM = 1 mS/cm2, gNaP = 0.04 mS/cm2, gh = 0, Iapp = 1.4 µA/cm2, σ = 0.032 µA×ms1/2/cm2. For σ = 0, the model neurons are at rest for this parameter set. With noise, the membrane potential fluctuates.
