Electrical appliance energy consumption control

摘要

A power control system that includes a plurality of electrical appliances and a controller. Each of the electrical appliances includes an energy storage device comprising a heat storage medium, a heater, and a temperature sensor. The heater is configured to heat the storage medium at a heating rate. The temperature sensor produces a temperature signal that is indicative of a temperature of the heat storage medium. The controller adjusts the heating rate of each energy storage device from a first heating rate to a second heating rate based on the temperatures of the heat storage mediums of the other energy storage devices.

1. A power control system configured to consume electrical power, at least a portion of which is generated from a renewable energy source, the system comprising:
a plurality of electrical appliances each comprising an energy storage device comprising:
a heat storage medium;a heater configured to heat the heat storage medium at a heating rate; anda temperature sensor that produces a temperature signal indicative of a temperature of the heat storage medium; and a controller adjusts the heating rate of each energy storage device from a first heating rate to a second heating rate based on the temperatures of the heat storage mediums of the other energy storage devices and a target temperature indicative of a desired temperature for the medium of the energy storage device; wherein:
the first and second heating rates are greater than zero; andthe second heating rates for the energy storage devices having lower temperature heat storage mediums are higher than the second heating rates of the energy storage devices having higher temperature heat storage mediums.
