Distributed electric power demand control
First Claim
1. A distributed load processing system for shedding and/or adding loads controlled by a plurality of processors for maintaining power demand by said loads below user established limits comprising:
- a common communication channel;
a plurality of processors connected to said common communication channel;
means for sensing the power consumption of said loads and for transmitting said power consumption to said plurality of processors; and
,each of said processors having demand limit means for establishing a demand limit representing a desired power demand limit, means for comparing the demand limit to said power consumption, and means for determining when a processor should shed and/or add its associated loads to maintain said power consumption below said demand limit.

Abstract
A distributed load processing system for shedding and/or adding loads controlled by a plurality of processors for maintaining power demand by the loads below a predetermined amount including a common communication channel, a plurality of processors connected to the common communication channel, a demand meter for sensing the power consumption per sample period so that the power consumption per sample period can be transmitted to all of the processors, wherein each processor compares the demand limit established for the system to the projected power per interval being consumed, and for shedding and/or adding its associated loads based upon this comparison to maintain power consumption per interval below the demand limit.

8. A distributed load processing system for shedding and/or adding loads controlled by a plurality of processors for maintaining power consumption by said loads below a predetermined amount comprising:
-
a common communication channel; a plurality of processors connected to said common communication channel; means for sensing the power consumption of said loads and for transmitting said power consumption to said plurality of processors; and
,each of said processors having priority means for establishing a priority sequence in which said processors can shed and/or add loads and for establishing the loads controlled by a respective processor in a tier arrangement for governing the sequence in which the loads of a processor are shed and/or added, demand limit means for establishing a demand limit representing a desired power demand limit, means for comparing the demand limit to said power consumption, and means for determining when a processor should shed and/or add its associated loads to maintain said power consumption below said demand limit. - View Dependent Claims (9, 10, 11, 12, 13)
