Dynamic Demand (electric Power)
Dynamic Demand is the name of a semi-passive technology for adjusting load demands on an electrical power grid. (It is also the name of an independent not-for-profit organization in the UK supported by a charitable grant from the Esmée Fairbairn Foundation dedicated to promoting this technology.) The concept is that by monitoring the frequency of the power grid, as well as their own control parameters, individual, intermittent loads would switch on or off at optimal moments to balance the overall system load with generation, reducing critical power mismatches. As this switching would only advance or delay the appliance operating cycle by a few seconds, it would be unnoticeable to the end user. This is the foundation of dynamic demand control. In the United States, in 1982, a (now-lapsed) patent for this idea was issued to power systems engineer Fred Schweppe. Other patents have been issued based on this idea.

Famous quotes containing the words dynamic and/or demand:
“Magic is the envelopment and coercion of the objective world by the ego; it is a dynamic subjectivism. Religion is the coercion of the ego by gods and spirits who are objectively conceived beings in control of nature and man.”
—Richard Chase (b. 1914)
“The laws of custom make our [returning a visit] necessary. O how I hate this vile custom which obliges us to make slaves of ourselves! to sell the most precious property we boast, our time;—and to sacrifice it to every prattling impertinent who chooses to demand it!”
—Frances Burney (1752–1840)
