摘要:
A power consumption distribution calculator uses a predicted outdoor temperature sequence of the customer house for a prediction period at a first date from a first time to a second time, and identifies dates having a sequence part similar to the predicted outdoor temperature sequence in the prediction period, identifies power consumption sequences corresponding to identified dates, and calculate a statistical distribution or a representative value of identified power consumption sequences for a whole period from a third time to the second time, the third time being earlier than the first time. A power consumption predicting unit calculates a predicted power consumption sequence in the prediction period based on the statistical distribution or the representative value. A reserve capacity calculating unit calculates reserve capacity being a difference between a predicted power consumption sequence and a sequence part in the prediction period of the reference power consumption sequence.

There is provided a consumption energy calculating device which simulates power consumption of a heating and cooling appliance operated by a customer living in a house. A first receiver and a second receiver receive a demand response signal and an external environmental factor parameter. A pain level model shows a relationship between an indoor air temperature and a pain level. A first calculator calculates, when the appliance is not in operation, the indoor air temperature of a next sample time. A second calculator calculates, when the appliance is in operation, determines the indoor air temperature of the next sample time. A working sequence generator determines whether the appliance is or not to be operated during the next sample time. The power consumption determination unit determines power consumption consumed by the appliance before the next sample time and outputs data showing the power consumption.
