Abstract
Abstract An add/shed system 10 to maintain the power consumption of a building below the predetermined level includes a plurality of loads A,B,C,D and means 38 for measuring the present total power consumption of the building. Processor 12 and computations section 40 reactively shed selected ones of the loads responsive to the measured total power consumption of the building to maintain the present power consumption of the building below the predetermined level. Processor 12 and anticipatory control section 42 determine the anticipated future increase or decrease in power consumption of the building and add or shed selected ones of the loads responsive to the measured total power consumption of the building and the anticipated future increase or decrease in power consumption of the building for continuously maintaining the power consumption of the building below the predetermined level.
