PROBLEM TO BE SOLVED: To provide a cogeneration system in which a thermoelectric cogeneration device is operated in such a manner that cost is reduced totally.SOLUTION: When information reception means 13 receives price change information, operation control means 7 of a cogeneration system sets an additional heat quantity to be newly generated by a thermoelectric cogeneration device during a first scheduling target period between a lower limit additional heat quantity that is determined based on a predictive heat load quantity during the first scheduling target period or more and an upper limit additional heat quantity that is determined based on a maximum heat storable quantity of a heat storage device 4 or more. Therefore, on the condition that the predictive heat load quantity during the first scheduling target period is supplied by heat that is generated by a thermoelectric cogeneration device CG, while referring to the price change information, a predictive heat load quantity during a period for cost calculation and total cost required for supplying the predictive power load quantity are calculated and such a scheduled operation time zone of the thermoelectric cogeneration device CG during the first scheduling target period that the total cost is reduced is determined.SELECTED DRAWING: Figure 1 |
