Optimal Secondary Control to Suppress Voltage Fluctuations in an HVDC-Linked Wind Farm Grid

IEEE Transactions on Power Systems, 2022
High-voltage direct-current (HVDC) systems using voltage source converters (VSCs) have been developed to suppress voltage fluctuations in offshore grids due to the intermittent power generation of offshore wind farms (OWFs).

Failure Prediction of Submodule Capacitors in Modular Multilevel Converter by Monitoring the Intrinsic Capacitor Voltage Fluctuations

IEEE transactions on industrial electronics (1982. Print), 2020
Modular multilevel converters (MMCs) are emerging as a promising topology for medium- and high-power applications. Aluminum electrolytic capacitors (AECs) are usually employed in MMCs as floating capacitors due to their high volumetric efficiency and low

A Coordinated Control Strategy for LCC HVDC Systems for Frequency Support with Suppression of AC Voltage Fluctuations

IEEE Transactions on Power Systems, 2020
In this paper, a new control method for a line-commutated converter-based (LCC) high-voltage direct current (HVDC) system to support the frequency and AC voltage was proposed. For coordinated control of the inverter and rectifier, droop-based controllers

Voltage Fluctuations of Neural Membrane

Nature, 1967
THE resting membrane potential of the frog Ranvier node shows fluctuations for which, between 1 and 10,000 rad/sec, the power/cycle of bandwidth is inversely proportional to frequency (1/f noise), and for frequencies of less than about 1 rad/sec there may be an increase in the negative slope of the plot of log noise power against log frequency1,2. This

Method for Determining the Droop Coefficients of Hybrid Multi-Terminal HVDC Systems to Suppress AC Voltage Fluctuations

IEEE Transactions on Power Systems, 2020
Different from voltage-source converter (VSC), reactive power absorption of line-commutated converters (LCCs) changes depending on DC voltage level.

Spontaneous Voltage Fluctuations in Glass Microelectrodes

IEEE Transactions on Biomedical Engineering, 1971
The spontaneous fluctuations of voltage across a glass microelectrode have been studied as a function of the average difference in voltage (V) across the electrode and the concentration of internal (n 2 ) and external (n 1 ) salt solutions. A stationary fluctuation was observed, with a mean square value many times greater than that calculated from the ...
