Voltage Response
In contrast to frequency, voltage varies widely throughout electric systems, because it is the voltage difference between two devices that largely determines the direction and magnitude of the current (hence the power) that flows between them. Therefore voltage is a more local phenomenon, and grid-friendly devices that respond to voltage will support more local aspects of the electric delivery system.

Famous quotes containing the word response:
“There is ... but one response possible from us: Force, Force to the uttermost, Force without stint or limit, the righteous and triumphant Force which shall make Right the law of the world and cast every selfish dominion down in the dust.”
—Woodrow Wilson (1856–1924)
