Claim:
1. A power demand adjustment system comprising: a control apparatus that measures a demand of electricity of a device associated with the control apparatus in a plurality of devices that receive a supply from a power grid as measurement information, sends the measurement information, and reduces the demand of the associated device by controlling a load of the associated device in response to the command; and a processing apparatus that stores an evaluation value for each of the plurality of devices, receives, prior to a predetermined plan period, first demand information that includes the measurement information for each of the plurality of devices, and first supply information that indicates a supply from the power grid, predicts a first demand amount which is an amount of demand from the plurality of devices in the plan period on the basis of the first demand information, predicts a first supply amount which is an amount of supply to the plurality of devices in the plan period on the basis of the first supply information, selects, on the basis of the first demand amount, the first supply amount, and the evaluation value, a candidate group, which is a candidate of a target of a load control, from among the plurality of devices, sends, to a communication destination corresponding to the candidate group, confirmation information that indicates a confirmation of the load control, upon receiving refusal information that indicates the load control is refused, excludes a device corresponding to the refusal information from the candidate group, after the selection of the candidate group, receives second demand information that includes the measurement information for each of the plurality of devices, and second supply information that indicates a supply from the power grid, predicts a second demand amount which is an amount of demand from the plurality of devices in the plan period on the basis of the second demand information, predicts a second supply amount which is an amount of supply to the plurality of devices in the plan period on the basis of the second supply information, selects, on the basis of the second demand amount, the second supply amount, and the evaluation value, a target group, which is a target of the load control, from among the candidate group, and sends to the control apparatus corresponding to the target group a command for controlling a load of the target group, wherein the processing apparatus, after the plan period, receives annoyance information that indicates a consumer felt annoyed with the load control, and calculates the evaluation value on the basis of the number of pieces of annoyance information corresponding to each of the plurality of devices, and wherein the processing apparatus, after the plan period, sends, to a communication destination corresponding to a device in the candidate group, result information that indicates a result of the load control, calculates an annoyance level, which is a rate of the number of pieces of annoyance information relative to the number of pieces of result information corresponding to each of the plurality of devices, determines a selection precedence for each of the plurality of devices under a condition that the selection precedence becomes higher as the annoyance level becomes lower, and selects any of the candidate group and the target group from among the plurality of devices in accordance with the selection precedence.
