SYSTEM AND METHOD FOR REDUCTION OF ELECTRICITY PRODUCTION AND DEMAND
First Claim
Patent Images
1. A method of altering a sum of power demanded on an electrical network comprising:
- accepting a power supply threshold of an electrical network in a period;
accepting a total power demand value of said electrical network in said period;
selecting a first portion of a plurality of power demand sources from which to reduce power demand in a first portion of said period;
selecting a second portion of said plurality of said power demand sources from which to reduce power demand in a second portion of said period;
wherein a reduction of said total power demand achieved from said reducing in said first portion is sufficient to prevent said total power demand value from crossing said power supply threshold during said first portion of said period; and
wherein a reduction of said total power demand achieved from said reducing in said second portion is sufficient to prevent said total power demand value from crossing said power supply threshold during said second portion of said period.

1. A method of altering a sum of power demanded on an electrical network comprising:
-
accepting a power supply threshold of an electrical network in a period; accepting a total power demand value of said electrical network in said period; selecting a first portion of a plurality of power demand sources from which to reduce power demand in a first portion of said period; selecting a second portion of said plurality of said power demand sources from which to reduce power demand in a second portion of said period; wherein a reduction of said total power demand achieved from said reducing in said first portion is sufficient to prevent said total power demand value from crossing said power supply threshold during said first portion of said period; and wherein a reduction of said total power demand achieved from said reducing in said second portion is sufficient to prevent said total power demand value from crossing said power supply threshold during said second portion of said period. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

13. The method as in claim A1, wherein said accepting a total power demand value of said electrical network in said period, comprises accepting a total power demand value from a portion of said electrical network in said period, said portion of said electrical network comprising a portion monitored by a single concentrator.

14. A method comprising:
-
calculating a reduction value of power demand, said reduction value sufficient to prevent said power demand from exceeding a power supply threshold in a period; designating a plurality of power demand sources suitable for power demand reduction; issuing a signal to reduce power demand from a first group of said power demand sources in said plurality during a first part of said period; and issuing a signal to reduce power demand from a second group of power demand sources in said plurality during a second part of said period; wherein during said period said reduced power demand is at least equal to said reduction value. - View Dependent Claims (15, 16, 17, 18, 19)

20. A system comprising:
-
a plurality of load control units, a first unit of said plurality to reduce power demand at a first power demand source and a second unit of said plurality to reduce power demand at a second power demand source; a processor suitable to; compare a power supply threshold to a total power demand level; calculate a reduction of power demand required to keep said total power demand from crossing said threshold; issue a signal to reduce power demand at said first power demand source in a first period; and issue a signal to reduce a power demand at said second power demand source in a second period, wherein said reduced power demand during said first period and said second period is greater than said reduction of power demand required to keep said total power demand from crossing said threshold. - View Dependent Claims (21, 22, 23, 24)
