<P>PROBLEM TO BE SOLVED: To determine a heat generation quantity of the day so that electricity cost is minimized. <P>SOLUTION: This heat storage control device has an actual database 31 storing a heat consumption actual quantity of a user of a plurality of days in the past, an assumption generating part 34 generating a candidate of a heat generation quantity generated at midnight by one or more as an assumption N, and a frequency distribution arithmetic operation part 32 determining the frequency distribution of the heat consumption actual quantity stored in the actual database 31 and calculating a probability X of causing a heat shortage in the daytime with every assumption N based on its frequency distribution, and also has an electricity cost arithmetic operation part 35 determining the sum total of an electricity cost expected value Cn (Yen) at midnight and an electricity cost expected value Cd (Yen) by additional generation in the daytime for every assumption N, an assumption evaluating part 36 determining as the heat generation quantity Na to be generated at midnight by selecting the assumption N of minimizing this sum total, and a heat generation control means 37 controlling starting or stopping of a heat generator 1 based on the heat generation quantity Na determined by the assumption evaluating part 36. <P>COPYRIGHT: (C)2009,JPO&INPIT |
