5 ways ultracapacitors operate in utility grids & microgrids
The net result of these factors is less grid stability. Ultracapacitors, also called supercapacitors, are rapid-response, high power energy storage devices that provide grid operators with a cost-effective strategy for addressing voltage, frequency, and power quality issues. Here are five ways that ultracapacitors can operate in the modern grid. 1.
