Abstract
A demand controller includes a microprocessor which is programmed to input data from switches on a control panel and output data to a set of eight circuits which control the operation of loads. Peak power demand is maintained below a preset DEMAND OBJECTIVE by selectively shedding these loads. The shed level for each load is not fixed, but instead, varies as a function of the rate at which total power demand is increasing. This rate is calculated by the microprocessor and the resulting shed level index (i) is employed to select the proper shed level for each load from a stored shed level matrix.
