Remote energy management to control household electrical appliances based on electricity pricing
First Claim
1. A demand response method comprising:
- generating first data comprising information about charge rates for a unit of power for respective time spans;
generating second data comprising information about amounts of power used for the respective time spans;
calculating, by a computer, third data comprising information about index power charges for the respective time spans calculated based on a combination of the first data and the second data; and
dividing the third data into a plurality of index sections such that dense index sections are generated in the time spans in which the index power charges are above a predetermined, index power charge threshold;
generating a Demand Response (DR) signal when use of the power is in an index section of the plurality of index sections in which each real-time charge for the power is present;
outputting the DR signal to an electric home appliance;
controlling the electric home appliance in response to receiving the generated DR signal,wherein the dense index sections are denser index sections, at least at a point in time, than others of the index sections, at the point in time, and the others of the index sections are below the predetermined index power charge threshold.

Abstract
A demand response system and method. The demand response system includes a power rate reception unit for receiving information about charge rates for a unit of power from an external power trading server. An amount-of-power used reception unit receives information about amounts of power used by a customer from a gateway, a first data generation unit which generates first data including information about charge rates for a unit of power for respective time spans, a second data generation unit which generates second data including information about amounts of power used by the customer for the respective time spans, and a third data generation unit which generates third data including information about index power charges for the customer for the respective time spans.

12. A demand response system comprising:
-
at least one hardware processor configured to implement; receiving information about charge rates for a unit of power from an external power trading server; receiving information about amounts of power used by a customer from a gateway installed in premises of the customer; generating first data comprising information about charge rates for the unit of power for respective time spans based on the received information about the charge rates; generating second data comprising information about amounts of power used by the customer for the respective time spans based on the received information about the amounts of power used; generating third data comprising information about index power charges for the customer for the respective time spans obtained based on a combination of the first data and the second data; and dividing the third data generated by the third data generator into a plurality of index sections such that dense index sections are generated in the time spans in which the index power charges are above a predetermined, index power charge threshold;
generating a Demand Response (DR) signal when use of the power is in an index section of the plurality of index sections in which each real-time charge for the power is present, to output the DR signal to an electric home appliance and to control an electric home appliance in response to receiving the generated DR signal,wherein the dense index sections are denser index sections, at least at a point in time, than others of the index sections, at the point in time, and the others of the index sections are below the predetermined index power charge threshold. - View Dependent Claims (13)
