Patent ID: 8868383

Claim:
A computer-implemented consumption energy calculating device which simulates power consumption of a heating and cooling appliance operated by a customer living in a house, comprising: a first receiver configured to receive a demand response signal specifying a power price; a pain level model showing a relationship between an indoor air temperature of the house and a pain level of a customer; a second receiver configured to receive an external environmental factor parameter including information concerning an outdoor air temperature of the house; a first calculator, including a processor configured to calculate, when the heating and cooling appliance is not in operation, the indoor air temperature of a next sample time based on the outdoor air temperature of the house and the indoor air temperature of the house, with respect to each sample time; a second calculator, including the processor configured to calculate, when the heating and cooling appliance is in operation, required power of the heating and cooling appliance to bring the indoor air temperature to a preset temperature before the next sample time, with respect to each sample time based on the outdoor air temperature and a coefficient of performance of the heating and cooling appliance, determine the indoor air temperature of the next sample time to the preset temperature when the required power is equal to or less than a predetermined maximum power, and calculate the indoor air temperature of the next sample time based on the outdoor air temperature, the indoor air temperature, the required power, and the coefficient of performance when the required power is greater than the predetermined maximum power; a working sequence generator, including the processor configured to obtain pain level based on the indoor air temperature for each sample time, calculates an evaluation value based on a weighted sum of the pain level and the power price, and estimate whether a user puts the heating and cooling appliance in operation or not in operation during the next sample time based on a comparison between the evaluation value and a first threshold; and a power consumption determination unit, including the processor configured to determine power consumption consumed by the heating and cooling appliance before the next sample time and output data showing the power consumption, the power consumption being determined to: the predetermined maximum power when it is estimated that the user puts the heating and cooling appliance in operation and the required power is greater than the predetermined maximum power; the required power when it is estimated that the user puts the heating and cooling appliance in operation and the required power is equal to or less than the predetermined maximum power; and a predetermined value when the user puts the heating and cooling appliance not in operation.
