Smart Grids and Power Quality
Modern systems use sensors called phasor measurement units (PMU) distributed throughout their network to monitor power quality and in some cases respond automatically to them. Using such smart grids features of rapid sensing and automated self healing of anomalies in the network promises to bring higher quality power and less downtime while simultaneously supporting power from intermittent power sources and distributed generation, which would if unchecked degrade power quality.

Famous quotes containing the words smart, grids, power and/or quality:
“Glorious the northern lights astream;
Glorious the song, when God’s the theme
Glorious the thunder’s roar:
Glorious hosanna from the den;
Glorious the catholic amen;
Glorious the martyr’s gore:
Glorious—more glorious is the crown
Of him that brought salvation down
By meekness, called thy Son;
Thou that stupendous truth believed,
And now the matchless deed’s achieved,
Determined, Dared, and Done.”
—Christopher Smart (1722–1771)
“New York ... is a city of geometric heights, a petrified desert of grids and lattices, an inferno of greenish abstraction under a flat sky, a real Metropolis from which man is absent by his very accumulation.”
—Roland Barthes (1915–1980)
“The power of a text is different when it is read from when it is copied out.... Only the copied text thus commands the soul of him who is occupied with it, whereas the mere reader never discovers the new aspects of his inner self that are opened by the text, that road cut through the interior jungle forever closing behind it: because the reader follows the movement of his mind in the free flight of day-dreaming, whereas the copier submits it to command.”
—Walter Benjamin (1892–1940)
“Emperor Joseph II: Your work is ingenious. It’s quality work, and there are simply too many notes, that’s all. Just cut a few and it will be perfect.
Mozart: Which few did you have in mind, majesty?”
—Peter Shaffer (b. 1926)
