Load reduction based on percentage change in energy price

摘要

A thermostatic controller generally includes a transceiver configured to receive a signal that includes an energy price rate for a given time period, and an electronic memory device in which one or more energy price rates received by the transceiver are stored. A microprocessor is configured to select the lowest energy price rate received within a given time period for establishing a base energy price rate; determine if the energy price rate for a present time period exceeds the base energy price rate by more than a first percentage or multiplier factor of the base energy price rate; and respond to an energy price rate that exceeds the base energy price rate by more than the first percentage or multiplier factor by transmitting a signal via the transceiver to an energy consuming appliance indicating that the energy consuming appliance should be in an off state and/or to one or more ceiling fans to activate, deactivate and/or change speed of the one or more ceiling fans.

1. A thermostatic controller comprising:
a transceiver configured to receive a signal that includes an energy price rate for a given time period; an electronic memory device in which one or more energy price rates received by the transceiver are stored; and a microprocessor in communication with the transceiver and electronic memory, the microprocessor configured to:
select from the one or more energy price rates the lowest energy price rate received within a given time period for establishing a base energy price rate;determine if the energy price rate for a present time period exceeds the base energy price rate by more than a first percentage or multiplier factor of the base energy price rate; andrespond to an energy price rate that exceeds the base energy price rate by more than the first percentage or multiplier factor by transmitting a signal via the transceiver to an energy consuming appliance indicating that the energy consuming appliance should be in an off state and/or to one or more ceiling fans to activate, deactivate and/or change speed of the one or more ceiling fans; wherein the microprocessor is configured to respond to an energy price rate that exceeds the base energy price rate by more than the first percentage or multiplier factor by transmitting a signal via the transceiver to an energy consuming appliance indicating that the energy consuming appliance should be in an off state; and wherein the microprocessor is configured to respond to an energy price rate that is below the base energy price rate by more than the first percentage or multiplier factor by transmitting a signal via the transceiver to the energy consuming appliance indicating that the energy consuming appliance should be in an on state.
