Capacitor operating current rating?
A high-current low-ESR cap is a good starting place if the cap will be subjected to high repetitive discharge currents. Also, for larger caps (>470uF) the ESR tends to get lower on caps with higher rated voltage.

A novel capacitor voltage fluctuation suppression method for the low
However, when the full-power variable speed pumped storage system is operating at the low-frequency stage, the voltage of the MMC sub-module capacitor fluctuates largely, which would lead to an abnormal operation state of the system [23]. This drawback limits the application of the MMC in the pumped storage systems.

6 FAQs about [Operating current of low voltage capacitor]
Does a perfect capacitor have a minimum operating voltage?
A perfect capacitor would not have a minimum operating voltage. However most capacitors are not perfect. Polarized types, especially electrolytics, may have altered characteristics at very low voltages as they have internal chemical layers that need to build up. They also have some leakage current that can be voltage and temperature dependent.
What is a low-voltage dry-type alternating current (AC) power capacitor?
This document provides standard requirements and general guidelines for the design, performance, testing and application of low-voltage dry-type alternating current (AC) power capacitors rated 1,000V or lower, and for connection to low-voltage distribution systems operating at a nominal frequency of 50Hz or 60Hz.
Do electrolytic capacitors need to be rated?
For electrolytic caps, they are (generally) able to withstand twice the rated voltage for 1 or 2 seconds. So, having the voltage close to its rated shouldn't be a problem. However... Like in other components, a capacitor's ratings need to be de-rated with external conditions (e.g. temperature).
Does this document pertain to low voltage oil-filled or direct current (DC) capacitors?
This document does not pertain to low voltage oil-filled or direct current (DC) power capacitors. 4.1 Capacitor internal design and construction Description of internal materials, dielectric, insulation, metallization, winding methodology and filling agent.
What happens if a capacitor is used near a rated voltage?
For an electrolytic capacitor, lifetime will be reduced close the the full working voltage. Many ceramic dielectrics lose their capacitance with DC bias (dropping to only 20% or less of nominal C is not unusual when used near the rated voltage). To an extent, capacitor voltage is nominal.
What causes low capacitance capacitors?
Eventually, they end up as low capacitance capacitors with very high ESR - the approximate end condition is an open circuit. An aging electrolytic may also develop low impedance between the electrodes - not usually a short, but a resistance in the right range to turn the capacitor into a heater.
