PROBLEM TO BE SOLVED: To estimate a variation amount of total output from a number of natural energy type distributed power sources from a little data by a simple method.;SOLUTION: Within an estimation target area, weather data and/or power generation output data are measured, and a power spectrum of power generation output from natural energy type distributed power sources and a power spectrum of average output are computed by using the measured data. Average coherence among variations of the power generation output from the natural energy type distributed power sources is calculated by using the power spectrums, and an index of a smoothing effect for each varying frequency in the case where the number of locations of the natural energy type distributed power sources is increased more than the number of measuring spots is estimated by using the coherence. A power spectrum of average output from the natural energy type distributed power sources in the case where the number of the distributed power sources is increased more than the number of measuring spots is estimated and a power spectrum of total output in the case where the number of distributed power sources is increased more than the number of measuring spots is estimated by using the index of the smoothing effect. A variation width of total output in the case where the number of distributed power sources is increased more than the number of measuring spots is estimated by using a standard deviation.;COPYRIGHT: (C)2014,JPO&INPIT
