Abstract

There is provided a data collecting apparatus in which a collector collects, from demanders, demand record data and demand forecast data of the energy; a data history manager; a reliability level calculator calculates, for each demander, a reliability level of the demand forecast data; a supply plan data receiver receives an acquisition request of demand forecast data of a future predetermined time range with respect to each demander from an energy management system; and a data acquisition plan maker makes a collection plan such that the demand forecast data of the future predetermined time range and the demand record data are collected earlier from a demander with a higher reliability level, wherein the data collector collects according to the collection plan, and the data history manager provides the collected demand forecast data to the energy management system before a start time of the future predetermined time range.

Claims

1. A data collecting apparatus comprising:

a data collector configured to collect, from a plurality of demanders, demand record data of energy and demand forecast data of the energy;

a data history manager configured to store therein the demand record data and the demand forecast data collected by the data collector;

a reliability level calculator configured to calculate, for each demander, a reliability level of the demand forecast data on a basis of the demand record data;

a supply plan data receiver configured to receive an acquisition request of demand forecast of a future predetermined time range with respect to each demander, from an energy management system that makes an energy supply plan; and

a data acquisition plan maker configured to make a collection plan according to the acquisition request such that the demand forecast data of the future predetermined time rage is collected earlier from a demander with a higher reliability level, wherein

the data collector collects the demand forecast data of the future predetermined time range, from each demander according to the collection plan, and

the data history manager provides the demand forecast data of the future predetermined time range collected by the data collector to the energy management system before a start time of the future predetermined time range.

2. The apparatus according to claim 1, wherein

the acquisition request indicates that the demand forecast data of each future time range is received at a constant time interval,

the data acquisition plan maker sets a larger number of cycles for collecting the demand forecast data, to the demander with the higher reliability level wherein a length of one cycle is identical to a length of the constant time interval, and the data acquisition plan maker the plan so as to collect demand forecast data of a corresponding future time range at an interval of the larger number of cycles and

the data history manager provides, with respect to a future time range not collected due to the plan, demand forecast data collected most lately to the energy management system.

3. The apparatus according to claim 2, further comprising a warning receiver configured to receive, from the demander, a warning that an error between the demand forecast data and the demand record data is equal to or more than a predetermined value, wherein

the data acquisition plan maker modifies the collection plan so as to shorten a cycle numbers of collecting the demand forecast data from the demander from which the warning is received.

4. The apparatus according to claim 1, wherein

the data collector collects a restrainable amount of demand and a demand restraint record from the demander,

the reliability level calculator calculates, for each demander, a reliability level of the restrainable amount of demand on a basis of the demand restraint record,

the data acquisition plan maker makes a plan such that the restrainable amount of demand of the future predetermined time range are collected earlier from the demander with a higher reliability level,

the data collector collects the restrainable amount of demand of the future predetermined time range, from the demander according to the plan, and

the data history manager provides the restrainable amount of demand collected by the data collector to the energy management system that controls supply-demand of the demander.

5. The apparatus according to claim 1, further comprising a data forecaster configured to calculate the demand forecast data on a basis of the demand record data collected by the data collector, wherein

the data collector does not collect the demand forecast data but collect the demand record data with respect to at least one of the demanders.

6. The apparatus according to claim 1, wherein

the supply plan data receiver receives information indicating data collection time from the energy management system, and

the data history manager transmits, to the energy management system, the demand forecast data of the future predetermined time range, on or before the data collection time.

7. The apparatus according to claim 1, wherein

the data collector, the data history manager, the reliability level calculator, the supply plan data receiver, and the data acquisition plan maker deal with demand scheduled data instead of the demand forecast data, the demand scheduled data indicating a scheduled amount of use for a demand of each demander.

8. A data collecting method comprising:

collecting, from a plurality of demanders, demand record data of energy and demand forecast data of the energy;

storing the demand record data and the demand forecast data in a data history manager;

calculating, for each demander, a reliability level of the demand forecast data on a basis of the demand record data;

receiving an acquisition request of demand forecast of a future predetermined time range with respect to each demander, from an energy management system that makes an energy supply plan; and

making a collection plan according to the acquisition request such that the demand forecast data of the future predetermined time rage is collected earlier from a demander with a higher reliability level, wherein

the demand forecast data of the future predetermined time range is collected from each demander according to the collection plan, and

the demand forecast data of the future predetermined time range collected from each demander is provided to the energy management system before a start time of the future predetermined time range.
