Optimal Secondary Control to Suppress Voltage Fluctuations in an HVDC-Linked Wind Farm Grid
IEEE Transactions on Power Systems, 2022High-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).

Estimation of Parameters Associated With Individual Sources of Voltage Fluctuations
IEEE Transactions on Power Delivery, 2020The paper presents research results on a novel algorithm that allows estimation of parameters associated with the specific voltage fluctuation sources in the power grid, which change their operating state with a frequency of up to 150 Hz.

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

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, 1967THE 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

Spontaneous Voltage Fluctuations in Glass Microelectrodes
IEEE Transactions on Biomedical Engineering, 1971The 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 ...
