20 Oct 1997TL;DR: In this paper, a demand electronic electricity meter having load profile recording capabilities is presented, where load profile parameters include the number of channels, interval size, quantities to be recorded (e.g., kWh and kvarh, kVAh, or Qh), and channel scalar/divisor.
Abstract: A demand electronic electricity meter having load profile recording capabilities is presented. Load profile recording requires memory for storing the recorded information, whereby either on-board memory or external memory is required. Load profile parameters include the number of channels (e.g., 1, 2 or more channels), interval size (e.g., 1, 5, 10, 15, 30 or 60 minutes), quantities to be recorded (e.g., kWh and kvarh, kVAh, or Qh) and channel scalar/divisor (e.g., for each channel, a 2 byte divisor and a 2 byte scalar). With two channels, only two quantities are available for recording, kWh and the one other quantity that the meter has been configured to record, (e.g., kvarh, KVAh, or kQh). For each quantity selected, snapshots of the corresponding total accumulator; (i.e. total kWh and total kvarh, kVAh or kQh) are automatically maintained.

TL;DR: In this article, a device for curtailing electric demand is proposed, which is suitable as a tool for responding to the real-time pricing of electrical energy or for reducing demand during power shortages.
Abstract: A device for curtailing electric demand is suitable as a tool for responding to the real-time pricing of electrical energy or for reducing demand during power shortages. The device ( 104 ) according to the present invention works in conjunction with an energy management system ( 40 ), which receives demand signals from an electric meter ( 24 ). Upon executing a curtailment command sent to the device ( 104 ) through a communications network ( 48, 50, 102 ), device intercepts and biases the signal going to the energy management system ( 40 ), which, in effect, coerces it to reduce the demand upon the meter ( 24 ) and upon the electric grid ( 20 ).
