Add/shed load control using anticipatory processes

A method of adding/shedding selected ones of a plurality of loads to maintain the power consumption of a building below a predetermined level, said method including the steps of:

• measuring the present total power consumption of said building;
• reactively shedding selected ones of said loads responsive to said measured present total power consumption of said building to maintain the present power consumption of said building below said predetermined level;
• determining the anticipated future increase or decrease in power consumption of said building by determining which of said loads will be required on or off during a preselected time interval and by determining which of said loads will be requested on or off during a preselected time interval;
• and
• predictively adding/shedding selected ones of said loads responsive to said measured present total power consumption of said building and said anticipated future increase or decrease in power consumption of said building to continuously maintain the power consumption of said building below said predetermined level.

An add/shed system for adding/shedding loads to maintain the power consumption of a building below a predetermined level, said system comprising:

• a plurality of loads;
• measuring means for measuring the present total power consumption of said building;
• first means for shedding selected ones of said loads responsive to said measured present total power consumption of said building to maintain the present power consumption of said building below said predetermined level;
• a second plurality of loads;
• control means for controlling the turning on and turning off of said second plurality of loads;
• and
• second means for determining the anticipated future increase or decrease in power consumption of said building and for adding/shedding selected ones of said loads responsive to said measured present total power consumption of said building and said anticipated future increase or decrease in power consumption of said building for continuously maintaining the power consumption of said building below said predetermined level wherein said second means is further arranged to alter the control of said second plurality of loads by delaying the turning on of said second plurality of loads by said control means when the turning on of said second plurality of loads would cause the power consumption of said building to exceed said predetermined level.
