Power supply and demand forecast automation system and power supply and demand forecast automation method

摘要

PROBLEM TO BE SOLVED: To provide a power supply and demand forecast with clear grounds and sufficient accuracy. SOLUTION: A process of specifying as a candidate date a day within a predetermined period from a predetermined prediction target date and matching a predetermined attribute of the prediction target date, and a candidate indicated by information on the candidate date or calculated from the information. The process of calculating the temperature difference between the representative temperature on the day and the predicted temperature value of the prediction target day and specifying a predetermined number of candidate days as the primary selection candidate dates in ascending order of temperature difference, and the temperature difference is the primary selection candidate date. The process of specifying the temperature difference related to the next smallest candidate date as the reference temperature difference, and the remaining candidate days excluding the primary selection candidate date among the candidate dates, and the temperature difference is within the predetermined temperature range from the reference temperature difference. In addition, the process of specifying one day with the same forecast target date and forecast weather and the smallest temperature difference among the remaining candidate days as the secondary selection candidate date, and the power demand on the primary selection candidate date and the secondary selection candidate date The actual value is acquired, and the representative value of the acquired actual value is calculated as the power demand forecast value on the forecast target date.
