POWER PROCUREMENT ADJUSTMENT PROGRAM, POWER PROCUREMENT ADJUSTMENT DEVICE, AND POWER PROCUREMENT ADJUSTMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method that, in minimizing a prior procurement plan for a plurality of scenarios considering a prediction error, creates a procurement plan in a sufficiently short time even when many restriction conditions are set.SOLUTION: A power procurement adjustment program, in generating procurement adjustment time series data to be a target of adjustment from a plurality of procurement time series data stipulating electric energy to be procured from the outside for each time, makes a computer execute processing that removes procurement time series data having a large total procurement amount from the plurality of procurement time series data to generate a plurality of applicable time series data, generates reference procurement time series data to be a reference for adjustment on the basis of expectation values of the plurality of applicable time series data in each time zone, and compares the plurality of applicable time series data with the reference procurement time series data to extract applicable time series data having a total procurement amount larger than that of the reference procurement time series data before taking the extracted applicable time series data as the procurement adjustment time series data.SELECTED DRAWING: Figure 2
