<p><P>PROBLEM TO BE SOLVED: To provide an energy attribute determination unit which can determine the attributes of energy consumption of apparatus uniformly. <P>SOLUTION: The energy attribute determination unit receives the data of power consumption (S11). The energy attribute determination unit divides the stored data of power consumption day by day to produce the data of the first day, the data of the second day, the data of the third day, and the data of the fourth day (S13), calculates a correlation coefficient of the data of the second day with reference to the data of the first day (S14), and then calculates an average value of the correlation coefficients of four days thus calculated, i.e., the average correlation coefficient (R), (S15). If the average correlation coefficient (R) is 0.8 or more (YES at S16), the attribute of energy consumption is determined as a fixed energy (S17), and if it is smaller than 0.8 (NO at S16), the attribute of energy consumption is determined as a fluctuation energy (S18). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
