Voltage Stability and Transient Symmetrical Fault Current Control of Voltage-Controlled MMCs [PDF]

open access: yesIEEE Transactions on Power Delivery, 2020
This paper presents a design-oriented analysis on the voltage stability and the transient fault current limitation of voltage-controlled modular multilevel converter (MMC) with L-filters. First, a dual-loop voltage control based on the L-filter plant is systematically designed, where the upper limits of controller parameters to ensure the small-signal ...

Transient Voltage Stability Assessment Method based on gcForest

open access: yesJournal of Physics: Conference Series, 2021
Abstract Aiming at the fact that the traditional method cannot quickly and accurately judge the power system transient voltage stability, and the deep neural network method needs many sample data sets and has a large number of hyperparameters, a power system transient voltage stability assessment method based on deep forest (gcForest) is

Sram cell stability metric under transient voltage noise

open access: yesMicroelectronics Journal, 2014
Abstract The conventional way to analyze the robustness of an SRAM bit cell is to quantify its immunity to static noise. The static immunity to disturbances like process and mismatch variations, bulk static noise, supply ring offset, quasi static temperature changes are well characterized by means of the Static Noise Margin (SNM).
